Lumix Diaries Leica 100-400mm Samples

Posted Jan. 23rd, 2016 by Daniel J. Cox

I’ve decided to share some images from the new Leica 100-400mm lens in this Blog post. There has been a lot of interest and requests from my readers to see  full-sized, high resolution images ever since the assignment I was given to produce ad materials for then new Leica 100-400mm zoom.

Sharing full-sized, downloadable images is not something I  typically do, but I feel it’s important for readers to see the quality I’m currently getting with the new lens. Keep in mind this was literally the first of two lenses Panasonic gave me to shoot the ad campaign. I’m told there are already several updates that show even better results. Not having a finished production model was another reason I had been putting this off but the quality of the prototype lens speaks for itself.

To protect my work I’ve included a very large watermark across the entire frame of each photograph. Though it is large, it does not affect the ability for a viewer to see the image details. To download these images you will need to go to this page: Lumix Diaries Leica 100-400mm Samples, and type in the password leicazoom to gain access. Once you type in the password, you will be able to download all ten images in a batch or individually. Looking forward to hearing what you all think. Stop back to the Blog to join the conversation.

Update 1/25/2016

Since I released the images for review I’ve taken some well deserved criticism for lousy post-processing of the sample images. After I checked my Export settings in Lightroom I realized I had the “Sharpen for Screen” setting turned on. That along with some sharpening applied in the main development process created lots of noise on a few of the images shot at higher ISO’s. I want to thank several readers over on the DPReview Micro Four Thirds Talk forum for helping me understand I needed to re-process these images. I specifically want to say thanks to Horst and Big Ga who both offered to process several of the images for me to show what could be accomplished. It was a great learning experience and with encouragement from the others, I took another stab at reprocessing the files.

Very unscientific comparison of the new Olympus 600mm F/4 and the new Leica 100-400mm zoom.

Very unscientific comparison of the new Olympus 600mm F/4 and the preproduction, prototype, Leica 100-400mm zoom. Thank you to Robin Wong. See his post on the new Olympus 300mm F/4

This time I decided to use DXO Optics Pro 10, and as usual I did very little to any of the files. However, I did use a small amount of noise removal for a couple of the pictures and also applied a small amount of sharpening. Overall I’m much happier with the results than what I achieved from my first attempt in Lightroom.  Admittedly I may have been able to achieve something very similar in Lightroom had I not accepted some of the default settings Lightroom automatically applied on Export. Not Lightroom’s fault, that was my error. I’ve replaced the first images that were poorly processed in the gallery titled Lumix Diaries Leica 100-400mm Samples.

This Blog post rapidly became very popular and many readers were quickly comparing my images shot with the 100-400mm Leica to the recently released images by Robin Wong who recently shared images from the new Olympus 300mm F/4. There is no question, the new Olympus lens is producing spectacular results, but to compare the two lenses I feel is a bit premature. Why? Because the Leica 100-400mm I’m currently shooting is basically a prototype, one of only two that was hand delivered, having been custom constructed on Panasonic’s Osaka headquarters optical bench. Based on what I’ve seen, regarding the new Olympus 300mm F/4, that lens is considerably further ahead in the development process and actually seems to be in full blown production. I’m confident that any issues we may see when comparing the two lenses, will most likely all be worked out in the final production of the new 100-400mm Leica.

Final Update 2/1/2016

As I mentioned in the last update this post had become very popular and I received a lot of suggestions about better processing techniques for the images I was showing as samples. Being the opened-minded guy that I am I agreed that I could use some help. So I reached out to one of the folks I was chatting with over on DPReiew, Horst Heppel. I invited Horst to process all the images as he would for his own work. He was gracious to take this project on and I’ve uploaded his samples which you can also download and use for your own personal review. I also asked Horst to provide a shot bio and description of how he processed this images. That information is below.

My name is Horst Heppel. I’m a retired Computer-engineer from Germany. I photograph since I was 12 years old. Started out with a Kodak-Box. With the beginning of my retirement, I switched from one of the big boys to MFT completely. Currently I use a GH4 and an E-M1 together with several lenses (primes and zooms) from both companies. Most shot subjects are: Sports and wildlife. I shoot raw only. With Photoshop and Lightroom I work since the beginning of the digital age.

Daniel explained already what the trouble with his 2015 pictures had been, too high, internal sharpening.
Sharpening in Lightroom is twofold. Internally a relative sophisticated raw-sharpen panel exists, with amount, radius, detail, masking, similar to the well known unsharp mask. But only similar. This is in practice more a first sharpening instance for the converted raw files.
A second sharpening instance is the output-sharpening during export of the converted images. It sharpens the complete image with three possible strengths (light, standard, strong) for screen and print. It works as intended, provided a good, not too strong raw-sharpening has been applied before. Many Lightroom users get confused about this feature in the Export window.
But no problem, one can leave that out and use instead a third-party tool or one of the lightroom plug-ins which exists for output-sharpening.
In my run with Daniels Raws, I applied a fairly light raw-sharpening with a mask and a light output-(export)-sharpening only. On a few sample TIFFs I did the output sharpening with a third-party tool, which gives more micro-contrast and is for many, more pleasant.

This will be my last update to this post. I don’t think we can do any more speculating in regards of which lens is sharper, the Panasonic Leica 100-400mm or the soon-to-be released Olympus 300m F/4. I plan on purchasing the new Olympus lens, so when I get one I’ll be running head to head tests. Thanks everybody for your interest in these two amazing new lenses. And a social thanks goes out to Robin Wong who graciously allowed me to use his images to makes some unscientific comparisons. You can see more of Robin’s terrific work with the Olympus system on his website.

    Dear Dan, Can you provide me with tips capturing moving / flying birds using 100-400mm / GX8?
    I assume greater than 1/1000 sec., continuous auto-focus, … what type of metering? Any tips would be appreciated

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn May. 9th, 2016

      Dan, typically, a good rule of thumb for shooting moving objets is to use a shutter speed equal to or greater than the lens you are using. So if you are shooting the 100-400mm Leica, you’ll want at last 1/1000th of a second shutter speed. I’ve also highlighted the settings I use on my GH4’s and GX8 bodies for birds flight in this Blog Post Let me know how it goes Dan.

  2. CraigOn Mar. 29th, 2016

    Picture quality from this lens is superb, the details on my bird photos are outstanding

      Craig, great to hear from you. Stop back and let us know how it’s working.

  4. RobertOn Feb. 11th, 2016

    Forgot to ask…..don’t you think images from real production models should be showing up somewhere with release date so close?

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Feb. 11th, 2016

      Not sure Robert. I do know that there are a few more of these lenses out and about but I’m told they are all preproduction models. I don’t see why preproduction is the only option until the date of the final production model release.

  5. RobertOn Feb. 10th, 2016

    Daniel, please posit a best guess. I just checked and B&H says release date March 15, Amazon still lists release date as March 25th.
    Me thinking you with the the finger on the pulse of Panasonic would know the reality. I’m just curious as it won’t be needed until end of May when we head to Svalbard.

    Also, for fun and prediction, many want to compare the Leica 100-400 with the Oly 300. I think you’d agree these are apples/oranges. When mine comes in I want to compare to my EOS 100-400ii….wouldn’t that be a much more logical comparison?

  6. AndyOn Feb. 8th, 2016

    Some very interesting shots which are not only sharp but with great contrast and colour. I’m very impressed with this lens so far and I may well buy one when its available. Of course, as an olympus EM1 owner, the Oly 300 is in contention. But I like the convenience of a zoom and the price!
    I can’t reliably get the sharp shots here, do you use a tripod in the main I wonder?

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Feb. 8th, 2016


      I very seldon use a tripod anymore except when I’m shooting video footage. The new 100-400mm is desgined for use with the Lumix GX8’s Dual IS and that has been a decent step forward. Looking forward to trying the final production lens with the GX8 to see if we get even better results than I’m getting with the current prototype lens.

  7. LouisBOn Feb. 7th, 2016

    Great review and indeed I have a pre-order in. I must be one of the few owners that found the 100-300 a great lens. I used it extensively for backyard birding and got some outstanding results but it is worth emphasising that it takes time, a lot of time to get good bird shots. In fact, I started the Flickr group dedicated the 100-300 and there are some good exemplars in that group of what the lens can do. I sold my 100-300 on a whim (to purchase a totally inferior product) and was on the verge of buying another when the 100-400 came to my notice. So, I am anxiously awaiting my pre-order.

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Feb. 7th, 2016

      Louis, the 100-300mm really is impressive for a $500.00US lens. That said, the new 100-400mm is a huge upgrade and the two lenses aren’t even really comparable. You won’t regret the substantial upgrade.

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Feb. 5th, 2016

      Agreed. There is an extra lens hood as part of helens package.

  8. Rick StockerOn Feb. 5th, 2016

    A final thought. Great photos may be lost for want of equipment but only photographers, not equipment, make great photos.

  9. Rick StockerOn Feb. 5th, 2016

    Comparing fixed focal length and a zoom lens is worse than comparing an apple and an orange. Expecting the Pana 100-400 at 300mm to be as sharp at the same f-stop as the Oly to me is fantasy. It might even require rewriting one or more laws of physics. But what about the Pana 100-400 at 400mm versus the Oly 300mm plus 1.4 Teleconverter? Or suppose the ideal focal length for a shot is 250mm. Which would be sharper, the Pana 100-400 at 250mm or the Oly 40-150mm with the necessary cropping?

    Personally I was hoping Oly would produce a 150-300mm zoom so with four lenses one could cover focal lengths 14mm to 300mm.

    Then there is the question of how much processing can reduce any inherent difference in two lenses.

    And finally, a spectacular photo using either the original Pana telephoto zoom or the Oly telephoto zoom would beat the pants off a mundane photo with either of the two new telephoto zooms.

    • Marshall F.On Feb. 8th, 2016

      Thanks for belaboring the obvious. However, knowing whether a telephoto zoom can at least *approach* the quality of a prime lens is indeed a worthwhile endeavor. It used to be that zooms never came close, but that distance is shrinking, and comparisons are indeed useful. Grateful to Daniel Cox for this.

  10. TomOn Feb. 5th, 2016

    Thanks for the review.
    I am not in birding but in nature as a whole. I like to improve my telephoto capacity to flatten things out and to pick subjects of Mountain or buildings. I don’t know what is the better choice, Olympus 40-150 or the Panasonic 100-400.
    Can you give me a clue?

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Feb. 5th, 2016

      Tom, it really depends on how much reach you need. I will tell you that the Olympus is probably the sharpest zoom I have ever shot and it may be the sharpest lens I’ve ever shot. If you don’t need the extra reach, the Olympus is a stellar choice.

    • GeorgeOn Feb. 22nd, 2016

      Yes, I agree with Daniel, the Oly 40-150mm f2.8 is a great zoom, sharp with very nice color rendering; I use it on a Pana GX7. The zoom is of very good build quality, smooth zoom and focusing ring. Excellent !

  11. Mike RonesiaOn Feb. 4th, 2016

    Some great stuff there. I have it on pre-order and am even more excited about it now.

  12. Chris BOn Feb. 4th, 2016

    Does this lens have an Arca-Swiss quick release base?

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Feb. 4th, 2016

      No it does not. But it does the one it has is removable which gives an option for third parties to build one.

    FYI you have the Only 300/4 identified twice as 600mm f4.

      Sorry, will try to go back and correct but no much time currently. Glad you knew what I meant.

  14. BillOn Feb. 4th, 2016

    Is anyone actually expecting a 4:1 zoom lens to match the optical quality of a comparably priced prime in the same focal length range? All I’m hoping for is significantly improved results over the 100-300 which I found to be so poor that I sold all my Pany gear and temporarily returned to Nikon.

    The early results with the new Pany look terrific and I appreciate all the hard work that went into creating these samples.

    Many thanks

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Feb. 4th, 2016

      I’m not counting it out as far as being equal to or better than a fixed focal length lens. Most likely you are correct but one can always hope. I can tell you it is much sharper than the 100-300mm.

  15. Steve HogeOn Feb. 4th, 2016

      Ste, let me give this some thought. It is an issue that would require me giving up my watermark. Will think about it. I like the idea of others being able to take a stab at post precessing since working with files has never been my strong suit.

    Dan —

    You are where you belong — at the top! I am proud to know The Man! Your astute observations and “backed by experience” comments on this new technology are invaluable to the Photo World. I hope everyone knows that you really know what the heck you write about unlike some photo “bloggers” who have never photographed a bison in -50 degrees or been chomped on by flies while photographing lions on the Mara. No Monday Morning Quarterback here. You are the “real thing!” A working photographer with a love of nature and a mind for technical detail. We owe you a great big giant THANK YOU! Can’t wait for you to do a head-to-head comparo of the PL 100-400 and the Oly 300 Pro! It should be very enlightening.

  17. Chris BOn Feb. 4th, 2016

    I’m missing the f/stop and shutter speed used, along with ISO data on the TIF or JPG downloads. Is it hidden somewhere? Could not find it in the EXIF.

    Thanks for the great post. I think the answer for me, will be a loaner or rental.

      Chris, not sure why you are not seeing any of the EXIF. I just checked all the files and it’s completely in place on my PhotoShelter account. Maybe something happened with the download. Might want to try it again.

  18. Boston COn Feb. 2nd, 2016

    Hi Dan,
    I guess at this point the consensus is Oly 300mm F4 is a bit sharper, not by a big amount but noticeable at 100%.
    Hope the Pany is working overtime to make the production units step a bit more. Meanwhile I found some sample images of the new Fuji tele 100-400mm F4-5.6, (review) (samples)
    The site is slow to get the full sized images. You may want to take a look and am curious about your assessment on the lens and comparison w Pany’s.

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Feb. 2nd, 2016

      Thanks Boston. I’ll try and take a look though I’m headed to Yellowstone and then off to Japan in the for the next month. Will be shooting the new Panasonic 100-400mm on an Olympus OM-D EM-1 to test for those that shoot Olympus. I will say that I’ve seen the Fuji 100-400mm and it’s a big lens. One of the reasons I switched to MFT was to reduce size and weight. I’m sure it will be a great lens other than size and weight. I’m confident Panasonic will release a superb lens. Thanks for stopping by to add your voice.

    thank you for providing this pictures. In comparison to the new Olympus there is the question which F-Stop has the Lumix at 300mm? Perhaps you paid attention to this fact?

    Thank you for your response!

      Reinhard, yes, I have paid attention. At 300mm (600mm equivalent) the lens is at f/5.6

  21. Jeff leeOn Jan. 28th, 2016

    In for a penny – in for a pound, ordered second Gx8 and pre-ordered the PL 100-400mm. My entire “serious kit” will be GX8 12-35 and Gx8 PL100-400 with a 7.5mm and Canon 500D closeup lens. I have other m43 lenses bu they are really for my EP5 air travel “normal” trips. I just hope that DFD/DUAL Is and sharpness is as good as I think it will be.

    I am eagerly awaiting your comments about using this lens on a Oly EM1 camera. I pre-ordered the Pana 100-400 after reading your Blog. I currently use the EM1 with a 50-200mm SWD +TC 1.4. Its a big step up from the Lumix 100-300 and I am wondering if the new Pana will be a step up from what I currently use for my bird and wildlife photography. I need to trade off size and weight against IQ because I do much of my wildlife shooting while walking trails or riding a bicycle. The new Pana seems to be about the same size and weight as my current rig but has more reach, and I would hope improved IQ. I also shoot with a Nikon D810 for IQ on landscapes and…, but its just too big and heavy to carry for wildlife.

      Daniel J. CoxOn Jan. 27th, 2016

      Paul, I too decided to make the switch from my very large Nikons to MFT. There is some minor loss of image quality but for most of my needs it’s not noticeable. And that’s even producing Fine Art Prints up to 24×36 inches. I’ve not had any experience with the Four Thirds 50-200mm but I’m willing to bet you will see a huge improvement in image quality and vastly superior auto focus. I have heard the Olympus 50-200mm is very sharp but it’s a fairly old lens and we all know that lens technology has not been standing still. Good luck with your new direction and let us know here on the Blog if we can be of any help.

    • David MartinOn Feb. 4th, 2016

      I picked up an Olympus 50-200 ED SWD 1:2.8-3.5 used. It didn’t focus very well with my OM-D EM-5, but provided an excuse to buy an EM-1 with a focusing system compatible with the older DSLR lenses. My first venture with that combination was at the local beach, where a skimboarder was, putting on a show, complete with flips. The hand-held results were spectacularly good, better than I could have done with the Olympus 75-300 or the Panasonic 45-200 O.I.S., so the lens has been in regular use ever since. I’ve just recently bought a 40-150mm 1: 2.8 PRO but haven’t had much chance to play with it due to a shoulder injury. It should be interesting to run comparisons.

      I assume that, as usual, firmware for the new Panasonic 100-400 mm zoom will be available from Olympus to make it play well with its cameras.

      Daniel J. CoxOn Feb. 4th, 2016

      David, you won’t regret the purchase of the Olympus 40-150mm. It is one of the finest lenses, if not the finest lens, I’ve ever used. I’ve been shooting it mostly on my GH4 since I purchased it and as long as I keep the shutter speed equal to or great than the focal length, I’ve haven’t missed the lack of IS. That said, I’m loving the superb Dual IS I’m not getting with the new Lumix GX8 and the new, soon to be released, 100-400mm Leica zoom.

    • GeorgeOn Feb. 22nd, 2016

      Quote “That said, I’m loving the superb Dual IS I’m not getting with the new Lumix GX8 and the new, soon to be released, 100-400mm Leica zoom.”

      Is this really what you wanted to say, “not getting” ? Maybe it should say:
      “That said, I’m loving the superb Dual IS I’m now getting with the new Lumix GX8 and the new, soon to be released, 100-400mm Leica zoom.”

    Daniel, (I wrote this als over at DPR)
    thanks for your quick response. Don’t get me wrong, all that is not any critic on your
    dedicated work. But I know my GH4 and I was suprised about some of the TIFFs grain, that I never saw in any GH4-Raw so far and your GX8 is newer.
    Yes of course, I would like to help you with my lightroom experience in converting the 2015 images myself. How can we accomplish this? The best thing would be a special password down- and upload. What do you recommend?

  24. SteveOn Jan. 24th, 2016

    Dan, these are excellent photos but they do not in my opinion exhibit the extraordinary sharpness and contrast I’ve seen from sample images taken with the Oly 300mm. However that’s not to say the lens is not excellent and with it having the flexibility of a zoom and being markedly cheaper is probably the best choice for most people.

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Jan. 24th, 2016


      Part of that may be my lack of skills in post processing. Stay tuned here on the Blog. I’ve reached out to one of our readers for help in redoing one or all of these images with quality post processing. I make no bones about the fact I’m not a software guy. I’m a photojournalist and with that comes lousy software skills. But I’m willing to learn as long as the photos are not taken out of reality. Will let you know how it goes.

    • MichaelOn Jan. 24th, 2016

      Thank you very much for posting these samples. I think the picture quality held up surprisingly well even at 400/6.3. Bokeh also seems surprisingly good, for a zoom. But I agree with Steve that some of the Olympus 300/4 samples I saw are a little bit sharper in my eyes. Both at 300 and possibly also with converter at 420. But then again, the PanaLeica is a zoom compared to a more expensive prime lens. So this is expected, really. The zoom flexibility, smaller size & weight and lower price make this lens an excellent compromise and probably the more popular lens of the two.

  25. horsthOn Jan. 24th, 2016

    meanwhile after checking the TIFFs over and over again, I isolated the 2015 pictures as the unnatural grainy ones. Looks like a converter problem in my eyes.

      Daniel J. CoxOn Jan. 24th, 2016


      As you and many others over on DPRevew have surmised, my software skills are nothing special. Those who read my blog on a regular basis and travel with me know, I’m not a fan of heavy handed post processing. I did very little to the sample photos we’re all discussing. One tool that was used accidentally, was on Export from Lightroom, I had the “Output Sharpening” set to “Standard” and “Screen”. Probably not the best choice since it’s a generic option that doesn’t take each image, camera model, etc. in to account. But for those wondering, I did use Lightroom. I did not apply any noise reduction, a couple of images had some cropping but nothing major, and the only sharpening was the auto sharpening tool on export I mentioned above.

      To make this a quality learning experience for me and others, I would be interested in sending you any one of the samples you choose, as the original RAW file, to have you work your magic so we can see what quality post processing can do. Would you be up for that? Let me know and thanks for stopping by the Blog to join the discussion.

    what Raw-Converter did you use. Most of the TIFFs show a fairly strong fine grain all over. Independently from the ISO.
    I can’t believe that this is the GX8 20MP sensors quality. Never seen from my GH4 this sort of grain. There went something wrong during post processing in my opinion. Has surely nothing to do with the lense. The sharpness seems good, only the mule deer picture has some bad quality, little contrast and a lot of grain.

    I had been a Nikon user for over 40 years, after 5 months of using the Gx8, I sold it all. This was the last piece I needed in my kit (a 7.5mm FE, the 12-35mm, and a wildlife/birding lens). I am sure the Oly 300mm is going to be a great lens, but I do a lot of video and this lens shooting 4K will be a tool like no other. DFD/Dual IS on the Gx8 and the ability to crop 75% on 4k and still have stunning 1080P means that “To Far” will become a very rare statement – also the zoom will give you perfect framing. Really, for a wildlife film maker this is a tool unlike any other.

    Stunned at the image quality and sharpness!!! 100-300mm is low cost but just not doing the job. I can’t wait till I get my hands on 100-400mm. BTW why is the TIFF files size so large? Did you take it raw and then converted to TIFF?

      Dan, yes the original file as RAW and coverted to Tiff.

    Works now Daniel, thanks.

    I can’t get there either, it just leads back to this page.
    Great pictures BTW, wish I could have been there.

      Brian have you tried it again? It should work now.

    The link under the blue text is incorrect… doesn’t take you anywhere except back to the top of this page.

      Should be fixed no Nick. Sorry about the problem.

    It’s not possible to get to the download page. Some kind of a loop.
