Olympus 150-400mm versus Sony 200-600mm

Posted Dec. 31st, 2020 (2 weeks ago) by Daniel J. Cox

Olympus 150-400mm versus Sony 200-600mm is starting this week. I’ve been waiting for this new Olympus lens for over a year. The development of the Olympus 150-400mm was first announced in January 2019 and my excitement has been hard to contain.

Ultimate magnification

The video above is a short introduction to the new Olympus 150-400mm zoom. I talk about how this new lens is comparable to the Sony 200-600mm. The Olympus has a bit more reach with a maximum telephoto of 800mm. And that’s without the built-in 1.2X teleconverter which gives this lens a maximum of 1000mm.

Light gathering qualities

The Olympus 150-400mm has a maximum aperture of F/4.5 across the entire 150-400mm zoom range. The Sony aperture is variable with F/5.6-6.3 with it being F/6.3 at 600mm. Add the 1.2X teleconverter to the Olympus and you get a 1000mm F/5.6. Do something similar to the Sony, add a 1.4X teleconverter, and you get 840mm at F/8. It all comes down to the Olympus having 150mm+ more magnification and a full stop more light-gathering power.

Stay tuned for an in-depth comparison

Over the next 10 days I’ll be shooting these two lenses side by side in remote areas here in Montana and Wyoming. I’ll be self-quarantining with just me, the animals, and my camera gear. Stay tuned for more information to come.

    Hi Daniel,

    I have the lens on order and am very interested in your experience with the lens, particularly the comparison to the Sony 200-600 full frame alternative. Do you have a feel for when you will be publishing your report?

    Best wishes, Peter

      I’m not sure Peter. I have the new lens on loa from Olympus. I’m unsure how long I’ll be able to keep it. If I can keep it until the end of January I’ll most likely be able to write something up by mid February. If not I’ll most likely wait until I get my own which may be quite a bit later.

    Daniel,

    Very excited to see you work on this field test. As an avid wildlife/nature/landscape photographer I was on the fence regarding the 150-400 from Olympus. In choosing between upgrading my E-M1 Mark II to an EM1-X and purchasing the 150-400 or expanding from MFT into FF with the Canon EOS R5 I decided to go with the Canon. The uncertain future of OM Digital had a very large influence on my decision. I just could not pull the trigger on a $7,500 lens without knowing how the back end service was going to be or really how long OM Digital was actually going to be around. I’m sure the lens is exceptional and I’m looking forward to seeing the results you produce with it.

    Cheers,
    Mike.

    The rub of a technical argument

    Some years ago, my wife and I joined the Royal Opimian Society in an effort to expand our knowledge regarding the fruits of Bacchus. With glee, we went to a couple of their wine and dine events and soaked up the dinner speaker’s monologue on the relationship between wine and food. We were downright giddy when we received an invitation to a private event exploring the wines of France. This must mean something to receive such an invitation.

    We got there to find two men in heated debate, no that would be an understatement, in personal verbal assault of each other, their parents and progeny, the size of their brains and penises.

    One apparently felt the wines of one region were superior to the other because the hills surrounding the river valleys were composed of natural rock whereas in the other region, over hundreds of years, farmers had brought rocks from the river up into the hills to serve as heat sinks to keep the grapes warm at night. The other felt that the soil of the second contained a different mineral composition, and the stones were inert. The grapes of region two were thus inferior/superior by nature to region one. It should be pointed out that I no longer remember the names of the regions being debated so vehemently that night.

    This argument went on endlessly. Frankly, it became boring. Eventually, someone opened some of the bottles and we were permitted to sample the wines. After a short field test, my conclusion was that both regions produced equally tasteful wine, perhaps due to the skill of the wine makers then? Indeed after two or three glasses of each, I could no longer tell the difference.

    The two gentlemen were, you see, geologists. They believed that rocks and dirt were the thing that made the difference between the regional products. Their deeply personal knowledge of the rocks focused their opinions, but ignored the grapes, the warmth of the sun, coolness of night, the wine makers, the yeast, the oak of the barrels and so many other factors critical to delivering the final result. And both results were just fine to my taste.

    The moral of the story is, don’t trust a geologist to help you choose your wine.

      OK Dennis. We shall see if this makes sense. Stay tuned.

    Nothing warming my heart more to see how a well established photographer is satisfied with the Olympus and Panasonic gear!
    About above mathematics I don’t trust it. From what I know, a 400mm F/4.5 Olympus gear behave like a full frame 800mm with an aperture of F/4.5 and it has a depth of field like a 800mm F/9 full frame lens, continuing the math gymnastics, it also have a depth of view like a full frame 400mm F/4.5 full frame lens! Happy New Year!!!

    Dear Mr. Cox,

    Been following your site for years…
    Your work has convinced us to take MFT serious, your information has always been on point and a welcome contrast to the mass hysteria online.
    This led to a lot of experience and results we otherwise would not have had…
    … including the addition of Sony FF to balance where MFT and Lumix FF sometimes lack.

    In that light there is no better source to answer the first question to MFTs (probably) last chapter:
    How much better is the 150-400…?

    Thanks for your effort and stay healthy.
    Kind regards from Austria,
    Marius M. Hintringer

    Danial,
    Your paragraph above “Light Gathering Qualities” is very misleading and I would say just plain wrong.

    The “light gathering power” of a lens is dictated by the square of the entrance pupil. In the case of the Olympus, the entrance pupil diameter is 400/4.5 = 88.9mm. The Sony is 600/6.3 = 95.2mm. So the Sony gathers (95.2/88.9)^2 = 1.15 = 15% more light than the Olympus. I’m not saying that this is a significant amount but still, the Sony gathers more light.

    You could correctly say that the Olympus has 200mm less focal length and is one stop brighter but you cannot say that the Olympus has “150mm+ more magnification and a full stop more light-gathering power”. The smaller sensor only collects one quarter of the light when compared to a 35mm sensor. The rest is “cropped away” to get that extra “reach”.

    I think you are right to compare these two lenses. I agree, they are quite similar and I look forward to your results. In terms of reach, the Sony on an A9II with 1.4x TC attached and cropped to the same number of horizontal pixels as the Olympus gives a full-frame equivelent image with angle of view of 600 x 1.41 x 6000/5184 = 979mm at an f-stop of 6.3 x 1.41 x 6000/5184 = f/10.3 vs the Olympus with internal teleconverter switched on of 1000mm at f/11. Quite close really!

    However, I’m expecting the Olympus to be sharper.

      Thanks for your insight Tony. You may be right regarding all that math you shared. I have no idea to be completely honest. I’m not a math guy. My brain has a tendency to default to the right creative side. So I’ll take your word for it and/or let others confirm or refute your position. Thanks for joining the conversation.
