Comparing Sony, Olympus, Lumix Telephoto Sharpness

Posted Dec. 18th, 2019 by Daniel J. Cox

Editorial Note: I’ve amended this blog post due to an overriding interest in the fact I’m no longer a Lumix Ambassador. In all fairness to the folks at Panasonic, I’m still a very big fan of their equipment and the Ambassador news was taking away from the real reason for this post. I’ll continue to share the benefits of the Lumix system as well as other systems I’m working with. All under the umbrella of a freelance tester with no ties to any company.

DIY lens tests – I’m not a scientist

Something I’ve always done is test lenes. It started with shooting brick walls behind F-11 Photo here in my hometown of Bozeman, Montana. A flat brick wall is great for tests due to it being an even plane with lots of details. I switched to the studio because of the potential risk of camera shake when using long telephotos.

Flash is the key to sharp DIY lens tests

Many photographers don’t realize a flash is a tremendous tool for stopping action. Any kind of action which includes shaky hands. Jim Harmer of Improve Photography explains the speed of a strobe light extremely well in his blog post. A quick FYI: Strobe and Flash are one and the same. As he shows, a typical strobe/flash that’s made for a traditional mirrorless or DSLR camera produces a very fast, intense blip of light when fired. Most professional flashes also have the ability to adjust the power of the flash output.

The lower the power, the faster the light emitted. This makes for what equates to a very fast shutter speed. Those of you who know photography understand that stopping movement of any kind will produce much sharper images. The faster the shutter speed used, the sharper your image will be. This is most important when shooting longer telephotos such as the Leica 100-400mm, Sony 200-600mm, or other telephotos/long zooms. Powerful telephotos are nothing more than monster magnifiers. They magnify the subject as well as ANY movement while taking the picture. And that’s why I use flash for testing lenses.

And this is how

One of the issues I had to solve was making certain the lens I was shooting was completely parallel to the test target. To accomplish this as close as possible I used two tools. One was LensAlign, and the other was a laser measuring device. Both were used to make certain the camera plane was as parallel to the newspaper as possible.

The laser measuring device was used to measure the distance between the sidewall and the middle of the newspaper. I did the same from the middle of the camera to the sidewall. Is this perfectly scientific? No, the wall could be slightly off. But it’s what I have available and I find it works quite well.

I’m no scientist, but I did stay at Holiday Inn Express last night

You may have noticed I keep reminding you my tests are not perfectly scientific. And that’s because I’m well aware of the folks out there who love the chance to try and show their intelligence by knocking others down. I’m putting them all on notice that I ALREADY know my tests are not perfect. That said, my test procedures offer the ability for the do it yourself crowd to get an idea for themselves.

In a perfect world, I wouldn’t have to do these tests. DXOMARK does a much more scientific version of these same tests. Unfortunately, they’re slow to get new lenses, and some lenses they never test all. For example, the newest Lumix camera they have listed, for pairing with the Lumix/Leica/Olympus lenses, is the Lumix GH3. That’s three camera generations back.

Lots of lenses tested for the big three: Nikon, Canon, and Sony. Not so much for Lumix. Very disappointing.

They do list the most current cameras, like the G9, under the camera tab. But the current cameras are missing when I go to the lens tab and try to add a lens to a camera. If you guys and gals know something I don’t on this subject please leave details below. If you can find any of the lenses mentioned in this video and are able to combine them to a current camera I would love to know how you did it. Click this link for DXOMARK website for lens tests.

The results

From the tests I shot, I found the Sony 200-600mm to be very sharp. Not perfect edge to edge but no issue I would be concerned about for serious work.

The Leica 100-400mm old and new were pretty much the same and both very good from edge to edge. My hope that the more recent sample was sharper was unfounded.

But without a doubt, the sharpest lens of the bunch was the Olympus 300mm F/4. Shooting it with the 1.4X teleconverter showed almost no degradation in image quality and was still very, very sharp edge to edge. It was almost the same for the 300mm with the 2X teleconverter. Not as good as the 1.4X but not a huge difference.

For those who need a nap, you can follow along in the videos I’ve created below. I did a comparison of all these lenses at 100% in Lightroom. If you don’t want to download the images yourself and go through them, these videos will give you an out. Be warned, however, you may nod off.

    Hi Dan, thanks for the article and the great work you are doing. I’m curious if you’ve used the Panasonic 200mm f2.8 on an Olympus body and how that compares to the Olympus 300m f4? I have an Olympus body and the Pan 200mm but I’m trying to decide if it’s worth selling the Pan 200mm to buy the Oly 300mm.

      Geoff. The Leica 200 mm is a great lens. However when I compared it to the Olympus 300 mm F4 it was not as sharp as the Olympus edge to edge. The Leica had some softness compared to the Olympus. I recently sold my 200 mm and replaced it with the Olympus 300 mm F4. As I’ve started moving towards Olympus and testing their lenses I found them to be sharper from edge to edge than the Panasonic Leica that I was using.

    Thank you very much Dan, I am M4/3 user. I have 100-400 Pana Leica one… and would like to upgrade to 20 MP body or lens 200-600 as I also have Sony A7 Mark 3…
    As we all know the Image quality in low light/high ISO situation the FF is much better….

    What is your recommendation?

      That’s a tough call. I am also, right now, trying to decide between micro 4/3 and the Sony 200-600 mm lens with two different Sony cameras. There is no doubt that the full frame cameras do better in low light and the new Sony 200-600 is relatively compact and relatively small. But so far, I’m finding that the Olympus system is much quicker and easier to use when things happen quickly. I’m planning to take the rest of this year to shoot both systems side-by-side and will eventually make my mind up. But it may not be till the end of this year. Sorry for the vague answer but I’m in the same boat as you are right now.

    Just a note on aligning lens with target for sharpness testing. You don’t need anything high-tech. Place a mirror on the target, and line up the camera so that the image of the lens is centered in the finder. That’s it. You’re now aligned with the lens axis perpendicular to the target. Lock down the tripod head or whatever you’re using to hold the camera, remove the mirror, and you’re good to go.

      Fabulous idea Bill. Thanks so much for sharing. Can’t wait to try this out. Will be redoing some of these tests in April when I return to Montana. Always appreciate hearing from my readers

  4. Lucas GuitinkOn Jan. 9th, 2020

    Hi Dan, thanks for all the wonderfull insight you bring to MFT users. I was wondering what tele option to choose for my GH5. A friend of mine has the 100-400 mm, but I didn’t like the stiffness of the zoom ring, and I find the slower apertures a problem when there’s not so much sun around. You then end up with higher ISO values.

    I considered the Oly 40-150, the Pany 50-200 and the Pany 200 2.8 tele lenses. Now there was a 1500 Euro offer for the 200mm with a 300 Euro cashback in the UK (including the 1.4 TC), so I couldn’t resist. I am extremely happy with this beautiful lens.
    As regard to sharpness, I have seen a lot of tests of these lenses on the web, and my impression is that it all is a big lottery! When you compare the more objective tests (including yours and those of optical limits and lenstip etc.) one will see incredible discrepancies. That seems to leave only one conclusion; there’s an enormous fluctuation in sharpness between individual copies of the same lens. Either QC has slipped severely or it is simply too difficult to get constant results when manufacturing them. Many copies have problems at one side of the lens, and sometimes the whole lens underperforms gravely (see the 100-400 test on Lenstip and compare it to Opticap Limits or to your own testing).

    There are numerous examples to point at. Your copy of the Oly 40-150 seems great, but when Cameralabs compared this lens with the Pany 50-200 the Pany was much sharper at the tele end. Your copy of the Pana 200mm 2.8 is good but not outstanding, where as the copy that Lenstip tested breaks all records…

    As a small comfort this fluctuation happens with other brands too, but according to Roger of Lensrentals, MFT lenses will show more fluctuation because of the way they are built. I don’t know if that’s true, but the tests on the web seem to confirm this.

    My own conclusion is this; test these lenses yourself and if you have a high performing copy then handle it with care and never sell it. If you get a lemon, send it back or sell it.

      Excellent info Lucas. Thanks for sharing. Very disappointing to think we can’t depend on getting a quality copy of any particular lens. I recently replaced my 50-200mm Leica based on my tests you’re referring to. I’ll be testing the new one to see how it compares. Thanks for joking the conversation.

  5. Dennis LindenOn Jan. 4th, 2020

    Hello again Dan. I have been off the blog for many months now but popped back on to read with some sense of internal vindication that you have found the Zuiko optics to be as good as I have known them to be. I for one would not shed a tear at the separation of your ambassadorship as, to many, the role of the ambassador is in fact to represent the “xxx” (country, company, whatever). This sort of automatically tags an ambassador as a “fanboy”. Your honesty was always apparent to anyone who listened to or read your words, and that was never going to “fit in” with an ambassadorship. I much prefer the unbiased approach as in reality, many of us actually do have several different tools for different purposes, and that’s the position of an honest broker. A good physician will not also be trying to sell a medicine, supplement or service. This permits one with a good character and honest mind to recommend the best of any category to the patient. The minute you work for a company, well, it takes a piece of your soul. So, I look forward to YOUR honest opinions in the journey we call life.


    PS, I’ve come back to Olympus and just purchased the 4 year, no 5 year old EM1m2 and love it, but use a Lumix GX85 as a backup body and on the street, along with the Leica 15. I am building up my PRO Zuiko lenses. I also have a Sony a7R3 with their fantastic 55, and good 28. I also use APS lenses 18-135 and 75-300 which gives me an 18 Mpx image that as you well know translates to about 16 Mpx in 4:3 ratio, which works just fine indeed for printing which I do to 16×20 and 24×30 inches routinely. No one ever asks what camera the photos are taken with.

      Sorry for the delay on this Dennis. This comment somehow went astray. I appreciate your feedback. My original interest in working with Panasoinc came from a desire to see a company I knew was going to be behind the eight ball, succeed. My hope was honesty would win out for the betterment of the Lumix line as well as for myself. Unfortunately they didn’t see it that way. I also liked being part of a team and it was even better that it was an underdog team. Now that that’s all behind me I’m having a blast testing all kinds of new things. I recently bought the Sony A9 (first version) and the 200-600mm. I’m thinking about the A7R MarklV with the 70-350 as you discussed. Will continue to use my Lumix gear for travel and things that don’t move all that fast. Thanks for stopping to add your insight. I always love hearing from my readers.

    Re: Panasonic G9 with firmware 2.0 and running dogs

    First, a small disclaimer. I am by no means a professional photographer. I might get a good photo but that’s generally due to a combination of luck and the number of times I pressed the shutter button. However, I do tend to shoot in manual mode and most of my photos are properly exposed (even if they aren’t great compositions).

    I’ve taken the Panasonic out for a spin around three weeks ago and I captured several photos of my dogs running. I wasn’t able to figure out how to get the Animal Detect mode working properly yet, I wonder if that might make an impact in the future as the software does recognize the dogs quite well. However, after some tinkering, I started shooting in burst mode H, with 1-Area AF-C and the Focus/Release Priority for AFC set to “Balance”, which is the default. The AF settings were SET1 with default settings but probably SET2 would be a better choice.

    I’ve used my only MFT lens, the Panasonic Leica DG 12-60mm f/2.8-4, for all the shots so I’m guessing this is a best-case scenario for this camera, especially with the amount of light available and the high contrast between the dogs and the background. However, virtually every shot was a keeper if you take into account just the autofocus so I’m really happy with the camera.

    Hope this helps 🙂

  7. Andrei MaximOn Dec. 30th, 2019

    Hi Daniel,

    Thank you so much for the detailed comparison. I’ve recently switched from a Nikon D7000 to a Panasonic G9 based on your reviews, especially the “speeding pooch test” since 80% of my photos are of black Labradors running to fetch a dummy while the rest contain fairly static subjects by comparison, like portraits.

    Since I got the G9 with the Panasonic Leica 12-60mm f/2.8-4 lens, I was looking to purchase a telephoto lens like the Olympus 40-150 or the Panasonic Leica 50-200mm and was slightly edging towards the Oly because of the constant aperture and the extra 10mm on the wide end which would make it a great potrait lens but was afraid to lose the DFD benefits. Have you seen any differences in autofocusing performance when shooting the Oly on the G9 as opposed to the using the PL 50-200?

    Also, I was very pleasantly surprised with the comparison between the Sony system and the Olympus system. I think both G9 and M1X have the same sensor so the results should be almost identical, with probably anedge to the M1X when it comes to autofocusing in several scenarios so the results should still hold. The great thing about the MFT systems is that I can easily purchase and use Panasonic or Olympus glass and, down the road, buy an Olympus body. I can’t do that with any of the other brand names like Nikon, Canon or Sony.

    Thank you for the reviews and hope you’ll have an amazing 2020!

      Daniel J. CoxOn Dec. 30th, 2019

      Andrew, thanks for the kind comments. If you’re shooting dogs running at the camera I would definitely stick with the Leica 50-200mm. The reason is due to Panasonic’s DFD AF technology. Unfortunately DFD is not available with the Olympus 40-150mm since DFD only works when using LUMIX lenses with LUMIX bodies. Additionally, with the LUMIX bodies we need alL the options available for quality predictive AF, which is what DFD is, since Panasonic struggles with fast moving subjects. How are your hit rates with running dogs? Have you updated your G9 to the latest firmware? Thanks for joining the conversation and I look forward to your response.

    Dan, I have been watching your videos with great interest as a subscriber on youtube. Thank u for these real world tests. It also confirmed some pf my observations while using G9 and OmD em1 MII . Like i had mentioned a few years ago on your blog, I continue to attest to the fact that you have never misled me with regards to your own experiences with any camera gear we have discussed. I think I am very happy shooting wildlife especially BIF handheld with olympus system and nikon d500 with their shockingly light 300PF and 500PF lenses. These two combinations provide me with enough redundancy and the perfect balance of size and weight for excellent travel and wildlife photography without breaking my back while walking long distances with the equipment. Even if they go out of business, I am quite content shooting these for many years to come.

    It sure is disappointing to learn of your experience with Lumix, but your candor is to be appreciated. I have always gravitated towards the Lumix brand and thought of them as the “underdog” in the highly competitive photo equipment business. After buying many of their point and shoots over the years, as a former Nikon DSLR user, I sold this equipment and adopted the G9 system. Since I don’t really shoot BIF, I have found the auto focus problems to be a non-issue and really love the size and weight. (Plus, the latest firmware does make a positive difference.) And just as I think you experienced, image quality was on par with just about everything out there?
    Having followed your blog a while, it seems you were well-pleased with the Lumix gear, and hopefully your initial enthusiasm and endorsements aren’t going by the wayside with this recent falling out. Thank you for the honest opinions.

      Daniel J. CoxOn Dec. 23rd, 2019

      Thanks Chris. So great to have you join the conversation. And no… my love of the Lumix system is not over. About the only thing I have an issue with is the lack of action capabilities. Otherwise, as you’ve found, they build a fantastic camera that is by far the easiest to use of ANY camera being produced today. The only company that comes close is Nikon. The ergonomics of the top-end Lumix gear, the G9, GH5, GH5S and also the new full-frame cameras the Lumix S1 and S1R are second to none. Nobody is putting the right buttons in the right places like Lumix. Add to that their domination in touch screen technology and superior Menu system and you get a great set of tools for many types of photography. Just not birds in flight at this point. And unfortunately, for me, that’s a problem. So… I’m trying some other products for specific shoots as I wait for Panasonic to finally get DFD to do what we need or move to a different AF system. In short, I’m still a huge fan. You’ll see more about Lumix gear to come but rest assured you’ll ALWAYS get the straight story.

  11. William H.On Dec. 22nd, 2019


    Hi, I’ve been a reader for about a year, but have never commented before. However, your story prompted me to write.

    While the situation with Panasonic was unfortunate, It reinforced my opinion of you as trustworthy and a person of integrity. It’s too bad that Panasonic chose not to view your remarks as informative and helpful in pointing out where improvements can be made. Any criticisms you have made in the past have always been diplomatic, fair and still supportive. The unwillingness to accept constructive criticism is not encouraging for the company’s long term prospects.

    I have a G85 and several Lumix and Olympus lenses. Others have pointed out how “primitive” the auto ISO feature is and it’s something I wish would be improved, but if what happened is indicative of Panasonic’s attitude towards its customers’ comments, I’m not optimistic about seeing it improved. Also, the latest firmware upgrade ignored my camera body. It’s not that old, so I’m not feeling that the company is appreciative of, or values, it’s customers. It appears to me that Fuji generally does that right to cultivate loyal customers.

    Anyway, I believe your readers are solidly behind you and appreciate your honesty and thoughtfulness. Thank you for continuing to inform and educate, as well as sharing your thoughts and interests!

    I think DxOMark went into semi-retirement when the then-parent company, DXO Labs, filed for bankruptcy last year.

    Just before that, DxOMark was spun off to an independent entity and seems to have lost its resourcing and capability.

    Hence you will see 21 lens tests in 2017, 2 in 2018, and 7 in 2019 (none since July).

    19 sensor (camera) tests in 2017, 7 in 2018, 8 in 2019.

    Only time will tell whether they will bounce back, or become mainly a legacy resource.

      Good info Grant. Makes sense based on how far behind their lens and camera combinations are. Disappointing since I using DXO PhotoLab for my RAW editing workflow. Hope they don’t go away. Thanks for joining the conversation.

  13. Chris FragapaneOn Dec. 22nd, 2019

    Yikes. I have always had a very high regard for Lumix, as sort of the “underdog” in the highly competitive world of photo equipment. In fact I have usually gravitated to the brand over many years for the point and shoots, and then eventually selling my Nikon equipment for the G9 system.
    Although your experience is disappointing to hear, it will not likely change the fundamental fact that the G9 (for example) is simply a great camera. For those who don’t shoot BIF, the auto focus issue is not a problem so we will trudge forward with the many other positives. Admittedly though, you being “fired” does diminish my opinion of the brand.
    I would trust though Dan, that none of this takes away your initial positive opinions of the Lumix equipment. But, unfortunately, like many relationships, sometimes things just go sour. Hope things will get patched up.

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Dec. 22nd, 2019

      My Goodness Chris, your experience with Lumix sounds virtually identical to mine. I also started small and eventually moved all the way up to their most professional products. I too eventually sold all my Nikon gear. All along the way, I had to temper my enthusiasm for their equipment with the reality that they didn’t have the long lenses I needed. Eventually, that problem was solved, but not the autofocus for action. I waited for that for as long as I could and then finally just had to bail. But… as you said, that has not diminished my enthusiasm for their products when not shooting fast-moving subjects. I still feel they build the finest camera from an ease of use perspective. They’re as durable as any camera I’ve ever used and their video, except for AF, is stunning. I’m planning to continue to use Lumix for many things, especially for my travel work where the compact and lightweight bodies are so enjoyable to use. I’m hopeful the LUMIX team will get their AF system up to speed and when they do I’ll be a happy camper. I really am still as big fan of the LUMIX system.

  14. Andy MilesOn Dec. 22nd, 2019

    Dan sorry to hear this, having used Panasonic since the G1 I too would like to see a model with phase detect. If not already done so you should touch base with Andy Rouse who also has a fondness for Polar Bears. He recently decided he wanted to be free from being a brand ambassador and left Canon. He’s currently enjoying the EM1x

  15. Mauro MorandoOn Dec. 22nd, 2019

    If you have a bad corner, you can shoot with a tripod and, after the “normal” shot, you can rotate the camera (using the collar) 180 degree: if the bad corner move it’s a lens problem, if it stay is a target alignment one.

  16. PeterOn Dec. 22nd, 2019

    It’s cheaper and easier to fire the truth telling messenger then listen and act. Only a good manager knows the value of honest criticism of a loyal employ/supporter/ambassador and will act positively on that.
    I am sorry to hear that you got a “bad” manager by Lumix office. Maybe they understand in a wile that the only good Ambassador is a truthful one. The one who can be honest and can push development.
    It’s not a bad thing if a comparison is showing the weak spots which needs to be addressed to.

    Good thing your credibility is now clear for all. And Lumix needs to understand that advertisement and ambassadors arn’t the same box. Advertisement can run around the truth a bit as long as you don’t lie but not telling all the facts. Someone who is liking your gear and is posting about it often can be supported by giving gear to test but not payed off to modify it’s opinion. If so then a ambassador is changing to a advertiser and lose it’s credibility fast.

    so Kudos’s for your guts.

  17. DanielOn Dec. 22nd, 2019

    I’ve got to wonder, it took Sony, Olympus and Fuji 3 generations of mirrorless cameras to nail their AF-C tracking. Using their 2nd gen X-T2 or A7ii for BIF was a real struggle.

    DFD is kind of in its second generation. Its AF-S was pretty much perfect from the get go, and recent firmware updates brought AF-C in video up to standard among 3rd gen options from Sony, Olympus and Fuji. So I wonder if it’s just a matter of time before Lumix have a camera that is as easy to use for BIF as the best of the rest. Perhaps the market doesn’t have the patience to wait.

      Daniel J. CoxOn Dec. 22nd, 2019

      I agree Daniel and in fact, I mentioned exactly that in a blog post back in November 2018. And I still believe Lumix will eventually get it, but I need it yesterday. My readers and travelers depend on me being stright with them. That’s really what made me realize I could no longer be patient. People I care about were spending their hard-earned money on a system I was using. For a very long time, I didn’t highlight the inefficiencies of the Lumix AF. I chose to be patient and concentrate on the other many positive things Lumix offers. But I just could no longer hold it in. For the benefit of my readers and NE Explorers, I needed to discuss what I was experiencing.

    Maybe I’m missing something, but I don’t seem able to download your full test images. I signed up and logged in, but the only download option was low res.

    I’d like to be able to compare them with the Olympus file upscaled to match the size of the Sony file. I think that would give a better indication of whether one or the other was actually capturing more fine detail.

    Sorry to hear your news, Daniel, and disappointed at the myopic stance Panasonic appear to have adopted by demoting you to the position of “former LUMIX Ambassador”, despite the sterling work you’ve done for them and the honest manner in which you’ve commented on the strengths and failings of their products. My lengthy business experience of companies which adopt that type of “I see no ships” stance to product issues is that they ultimately fail and, unless Panasonic listen to not only you but many, many users of their photographic products, who echo your conclusions about the failings of the autofocus system they have adopted, they will, inevitably, see a mass migration of users to other camera makes. Very short sighted and so sad and unnecessary.
    Keep up the good work.

      Thanks for the kind words Bob. It’s all worked out for the best. My viewers, readers and folks who travel with us have come to trust my judgment emphatically. It’s that trust that has allowed me to build a reasonable following and completely sold out tours almost two years out. I owe it to these people to be absolutely fair and honest. That’s a good thing since I’ve never been able to do anything different. Full steam ahead!

    Well, Dan, you know the old saying, “There’s none so blind as those who will not see.” Good for you for standing up for what you think is right!

    “Tell me what I want to hear or I won’t listen to you.” If Panasonic wanted to improve their products they’d listen regardless of the message. While Panasonic apparently doesn’t want to hear your views, thousands of photographers (10s of thousands?) have and will continue to do so. I have written on several forums that you have proven to be an honest, reliable, objective, and thorough “evaluator” of gear. Wear your “fired Lumix Ambassador” badge with pride.

    I confess that, after investing in the Lumix GH5 system and the 100-400 lens, I’ve been very disappointed in that glass (especially after having been a Nikon pro for so many years). The 4K 60fps is important for my filming needs, but the incredibly slow telephoto (and the fact that I had to send it back for a complete cleaning at almost the cost of the lens due to dust intrusion) is pretty useless. Now I have too much money invested into the system (including an underwater housing) and can’t really afford to get into another faster system. I miss being able to film animals in motion and capture them sharply. 🙁

      You should take a look at some of the Olympus lenses Beth. That’s the beauty of the MFT system. You do have other options and still shoot MFT.

    Thanks for the test Dan. I have found that a prime lens always has the best image quality as long as you don’t need the flexibility of a zoom. It will be interesting to see how the Olympus 150-400 compares once it has been released.
