  • it's all about the reach, works fine on a G9, comparison to Panasonic 100-400 (with 2nd gen notes)
Style: Single
I had been considering getting a 100-400 lens for a while, but it was hard to justify. I already have the first generation 100-300, and picture quality aside, how much of a difference would it be to go to 400? Factor in the teleconverter options for the Olympus lens and it becomes easier to justify going to 560 (1.4x400) or 800 (2x400). I bought this lens and the 1.4 teleconverter, figuring it would be easier to use and less detrimental to picture quality than the 2x teleconverter. Owning a Panasonic G9, the first concern is how well the Olympus would work with it. Some reviewers say it's fine, others say the Panasonic 100-400 works so much better. With the Olympus 100-400 on its own the G9 seemed to perform just fine. I didn't notice any slow focusing or missed shots due to camera shake, even on an overcast day without much light. On this same overcast day I then added the 1.4 teleconverter and didn't find the lens any more difficult to use, other than finding a shot when fully zoomed. To know for sure, I also tried a Panasonic 100-400, and didn't notice any obvious advantages. I am sure shooting style can make a big difference in noticing how well a camera pairs to a particular lens, but for my amateur, handheld bird shots, I didn't have problems with either lens. It's hard to make comparisons with fast moving birds, but I did a test with the more stable moon. For this test not only did the 560 mm equivalent focal length better fill the sensor than the 300 mm lens, but it looked so much better. After seeing the difference in picture quality the cost was easy to justify, even without the reach of the teleconverters. The Olympus with and without the teleconverter and the Panasonic 100-400 were all clearly superior to the 100-300. I also found that the Olympus with and without the teleconverter looked better than the Panasonic. There are many reviews and posts comparing these lenses, with conclusions supporting one or the other, so pick either lens and there is ample documentation to show you made the right choice. Between lens copy variation, camera type and settings, and shooting style, there are plenty of reasons why one may work better for one person than another. For me, my simple moon test (which is repeated regularly looking for eclipses and such) showed the Olympus worked better, and in other testing the Panasonic did not show an advantage, other than size and weight, so I went with the long reach of the Olympus. In full disclosure, I wanted justification for the Olympus because of the teleconverter option, and in my case it did appear to look better. I experimented with the electronic teleconverter built into the G9 and cropping from both brands of 100-400 and the 100-300, but found that the 1.4x teleconverter pictures of the moon looked slightly better than the resized versions without the teleconverter. An undeniable advantage of the Panasonic lens is the size and weight, but it's not as much as specifications initially show. Sure, it's lighter, and that doesn't change, but its length does. The Panasonic is shorter than the Olympus when it is retracted and extended, but it is shorter by 1.5" retracted, and only a little over a half inch when extended. In other words, when at full zoom, the Panasonic is almost the same length as the Olympus. This is an aspect of the size that needs to be considered, though there is no doubt that retracted it more easily fits into a bag. The zoom length may also be related to the oft reported stiffness of the Panasonic zoom ring. The Olympus extends about 2 3/8", while the Panasonic extends about 2 7/8". That greater extension while zooming the Panasonic may account for the greater effort to twist its zoom ring compared to the Olympus. The handle is easily removed from the Olympus by loosening the finger screw and rotating the handle until it can slide off. This makes the lens feel much smaller, but it should still be held firmly with your hand, and not be support only by the camera's lens mount. length retracted; length extended; lens extension Panasonic 6 5/8", 17 cm; 9 5/8", 24.5 cm; 3", 7.5 cm Olympus 8", 20.5 cm; 10 3/8", 26.5 cm; 2 3/8", 6 cm I also found the Olympus focus ring to be easier to turn. This may seem trivial, but these large lenses require extra support, so it can be awkward to have a firm hold on the lens with a light touch on the focus ring. The Olympus focus ring is light enough that a free finger can easily focus on the bird among the leaves without shaking the camera, unlike the Panasonic which requires greater effort. The build quality of the Olympus feels great, and of course the all metal construction of the Panasonic lens does, too. I have read a few complaints about the durability of the Panasonic lens, but the one I tried was used, graded as "acceptable", and well worn, but still seemed to work as designed without any noticeable degradation to the lens mount or focus speed. Based on my short experience with the Panasonic, testing a copy that appears to have been used for a few years, I wouldn't hesitate to buy one if it were my choice. Several people with Panasonic cameras have also commented on the tightness of the lens mount. Yes, the Panasonic 100-400 feels a little more snug on the G9 than the Olympus 100-400, but I have other Panasonic lenses that are looser than this Olympus, and my tightest mounting lens is an Olympus 60 mm, so in my experience one brand isn't clearly better in this regard. The copy of the 1.4 teleconverter I have fits tighter to the camera than the Olympus lens does, so lens fit is even less of an issue, but for me it isn't an issue at all, either way. I was attentive to this when trying out the lens, and did notice some very (very) light clunking, but found most often it was related to the extended part of the zoom making a slight movement as I walked. The end of the Panasonic lens, though its extension is longer as previously noted, feels a little tighter in this regard. I thought when I tried these lenses that they would feel absolutely huge, but after acquiring the Panasonic 10-25, which was larger than all of my other lenses, and so good that it rarely leaves my camera, I didn't find them to be ridiculously large, at least when retracted. Fully zoomed, yes, they start to look pretty big, and all of these lenses, including the aforementioned 10-25, may make you wonder why you are using a micro four thirds camera (of course, you know that full frame lenses with comparable zoom would weigh even more). The Panasonic does come closer to the size that you might think a super zoom would be on a micro four thirds, and might tempt you into thinking it's a lens attached to your camera, but with the Olympus there is not doubt, it's a camera attached to your lens. This review should have been posted nearly a year ago, and now that I am finally getting around to it, I see there is a newer version of the Panasonic 100-400, which of course brings on another bout of "did I get the right lens?" With my initial investigation, I think I still would have bought the Olympus. The new Panasonic is shorter than the first generation when extended, which of course provides a size advantage, and also may address the zoom ring stiffness as I described above. A huge benefit of the 2nd generation is the ability to use teleconverters, but on the video I saw, the zoom range is limited with the teleconverters attached to prevent the lens elements from bumping into the teleconverter! This means the new Panasonic lens is not fully compatible with the teleconverters, and uses a switch to limit range to avoid mechanical interference. The Olympus can be fully zoomed in and out with the teleconverter. I like to leave the teleconverter on, and certainly wouldn't want to remove my lens to remove the teleconverter if the subject was filling the frame too much and I couldn't move. So, based on a couple of press releases, I still choose the Olympus. ... show more

  • Very pleasantly surprised
Style: Single
This is not an Olympus PRO lens but the build quality is very good. I am extremely pleased with the picture quality, in particular with the excellent image sharpness. I have also used the lens with the Olympus 2X converter and, again, I am getting pictures of a quality I would not think possible with this combination. Another surprise: the image stabilization works well. I was taking pictures at 800mm (with the 2X converter) - which is difficult to do hand held at a relatively low shutter speed - and most of the images came out quite nice! On the downside, the maximum aperture of this lens is a somewhat limited f/5.0-6.3 (worse when you add the 2x converter) and, given that, an ISO in the 6400 range may often be required. Even at this higher ISO, though, I am very pleased with the quality of the images I am getting from the combination of this lens and my Olympus OM-D E-M1 Mark II camera. For me, this is a pricy lens and I thought long and hard before purchasing it, but I'm glad I did. ... show more

  • Great lens except for manual focus
Style: Single
Tried my new Oly100-400mm from Amazon with my Oly OMD E-M1 M2 at the zoo yesterday and am very pleased with my pics, many shot at 1/2000 since these animals were all moving around. The continuous autofocus was right on target, very pleased with that. The manual focus on the other hand is quirky being "fly-by-wire" as I understand it rather than mechanically driven. So I had to hunt to get my subject in focus when in manual focus, not good when trying to quickly get a moving animal behind a fence in focus. If you turn the focus ring a bit past the best focus, and then try to return to that spot the image is not in focus, so then you have to hunt again. Very annoying! Other than that, I'm very pleased. ... show more

  • A lens like this is keeping MFT alive
Style: Single
It’s now mid 2024 and camera competition has been tough on MFT (Micro Four Thirds). Lots of people are saying MFT is dead but I beg to differ thanks to lenses like this one. Pair this lens with the Olympus/OM Systems OM-1 (Mark 1 or Mark II) or Panasonic G9II and you’ll have a great lightweight wildlife setup. Some of the cons of this lens is it’s slightly bigger and heavier than the Panasonic 100-400mm lens. Also this lens does not have Sync-IS with Olympus cameras. I feel the cons can be forgiven given the performance of this lens. I was using an Olympus 75-300mm lens and Panasonic 100-300mm II lens prior and this lens is a major step-up to those lenses. I’m currently using this lens with an Olympus OM-1 camera and I'm extremely happy with the images I’m getting with this combo. All attached photos are taken by me with the Olympus combo. My primary wildlife setup has been my Sony A7III pair with the Sony 200-600mm but I’ll be honest, I have been grabbing this combo over that Sony combo due to the light weight and excellent image quality. The Olympus combo balance well and doesn’t feel front heavy like my Sony combo. Yes, I can get better image quality with the Sony combo but I get less fatigue with the Olympus combo and I enjoy using the Olympus combo more than the Sony combo. Now keep in mind this is a 200-800mm full frame equivalent lens so at 400mm (800mm full frame equivalent) you must use proper technique to get the best image quality. Trust me, I’m still learning as I’m no pro. Practice, practice, and practice some more. I honestly feel wildlife photography is MFT strong suit. And thanks to lenses like this, I feel MFT will continue to live on. ... show more

  • Great super telephoto lens for the price
Style: Single
Not too heavy or large for telephoto range, great for bird photography, sharp and clean when there is enough light, focuses fast and reliably, well made and sturdy. Limitations become apparent on a cloudy or dark day when higher ISOs are required leading to increased image noise. There are brighter super telephoto lenses out there but are much much more expensive, much bigger and much heavier. The Olympus 100-400 is the best choice for advanced amateurs but professionals may need to put up with the weight, bulk and expense of brighter super telephoto lenses. ... show more
