Beautifully made - and large
First of all, this is an amazing lens; it is beautifully made and functions really well. Second, it is large; much larger than I expected. Please see the attached picture. The other lens is an Olympus 70-300 and it looks miniature. The picture of the tulip was in evening light and handheld. The detail looks great. The porcupine was taken with it eating in its den and I think the lens handled the low light well. The goat was an outside shot. All shots are handheld. I would really recommend this lens! As an addendum, my Manfrotto tripod would not smoothly mount to the lens foot. The Manfrotto plate has a lip that prevents the foot from lying flat. I purchased a Manfrotto Quick Release Plate with 1/4" Screw Quick Setup Kit for $12.50 and the problem is solved. Now the tripod and lens work together perfectly.

    4.0 out of 5 stars Très bon... si on accepte ses limitations
    Reviewed in Canada on August 11, 2023
    Verified Purchase
    Disons-le tout de suite, ce 100-400 (200-800 en équivalant 35mm) est un objectif lourd, encombrant, et coûteux, qu'on n'utilise que dans des circonstances bien précises, et en particulier pour la photo d'animaux.

    En tant que tel, il s'intercale entre les 75-300 Olympus et 100-300 Panasonic, bien plus petits, plus légers et moins chers, mais plus limités en portée et en qualité d'image, et les 300mm Pro et 150-400 Pro Olympus, optiquement meilleurs et plus lumineux que ce 100-400, mais destinés à un usage strictement professionnel vu leur poids et leur prix stratosphériques.

    Le professionnel sans contrainte de budget choisira assurément ces derniers, en sorte que ce 100-400 vise plutôt le marché des amateurs éclairés, ou des semi-professionnels malgré tout préoccupés par leur budget

    Pour ceux-là, la question de savoir si ce 100-400 est réellement justifié est néanmoins difficile à trancher. Si vous êtes satisfaits de votre 75-300 ou 100-300, si vous ne les utilisez que de temps en temps, et si vous ne voulez pas casser votre tirelire et vous compliquer la vie à transporter un objectif aussi volumineux et pesant que le 100-400, la réponse est clairement non.

    En revanche, si vous voulez disposer d'un objectif offrant malgré tout une plus grande amplitude, une meilleure qualité d'image, une excellente protection contre la pluie et la poussière et - sur un boîtier Olympus du moins - d'une double stabilisation objectif/caméra, le 100-400 demeure un objectif recommandable : monté sur un gros M1X, je suis ainsi parvenu à réaliser avec lui d'excellentes photos de baleines à main levée, et à bord d'un simple canot à moteur qui montait et descendait au rythme des vagues

    2.0 out of 5 stars Bad copy?
    Reviewed in Canada on September 29, 2022
    Verified Purchase
    I bought this lens on 鶹 two weeks ago when it was on sale for CDN$ 1,657.13. It arrived in a box that was slightly larger than the factory box with no padding to fill the gaps, which is very unusual for 鶹 that usually does a much better job packing far less expensive and less fragile purchases.

    Despite my high expectations I was really disappointed by the sharpness and overall image quality of this lens after comparing test images shot with it vs my old first-gen Panasonic 100-300 lens that's 40% the price, weight and size of the Olympus 100-400.

    I made two batches of tests, one handheld with both the optical image stabilization in the lens and the sensor IS in my E-M1III turned ON, and the other mounted on a tripod with both image stabilizations turned OFF. In both cases I tested the lenses at 100mm, 200mm and 300mm with the aperture wide open (different between the two lenses and at different zoom levels), at the sweet spot (f7.1 for Panasonic and f/8 for Olympus), and at f11. For every combination of lens, focal length and aperture I made two series of burst shots using the electronic shutter and remote trigger to minimize shake. Finally, all shots were made using auto focus because that's what I mostly use when shooting birds and wildlife using telezoom lenses.

    The images shot with Olympus 100-400 at best matched my Panasonic 100-300 in the tripod tests, and consistently underperformed in the handheld tests in terms of sharpness and clarity. I published the test results on my personal blog but 鶹 wouldn't let me post the URL in my review.

    Given the glowing reviews of this lens by many reputable online reviewers I assumed I got a particularly bad copy. I then asked 鶹 to exchange the lens but was told that I could only return it for a full refund, which is what I did.

    Curiously enough, I noticed that just a week after I ordered my lens its price went up by a whopping CDN$500 which makes me think that perhaps 鶹 was selling off some leftovers that were known bad copies, or copies previously sold and returned due to their poor quality. As usual, buyer beware!

    Praticamente perfetto, nitido a sufficienza (qualche decadimento assolutamente minino agli estremi) per foto di alta qualità, compatto e resistente, anche se non classificato come pro un obbiettivo con caratteristiche di alto livello, stabilizzato e tropicalizzato. In più può montare i moltiplicatori Olympus (1,4x e 2x) che aumentano il range fino alla incredibile focale di 1600mm (FF equivalenti), cosa che il suo "parente stretto" Panasonic (anche se di altrettanta qualità) non può fare.

    5.0 out of 5 stars it's all about the reach, works fine on a G9, comparison to Panasonic 100-400 (with 2nd gen notes)
    Reviewed in the United States on October 14, 2023
    Verified Purchase
    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.

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.

    My 'walkabout' bag for when I am visiting home on the West cost of Scotland comprised an OMD-EM1 mk2, a 12-100mm zoom, 40-150 PRO zoom and a 1.4X teleconverter. I found that I didn't have the reach for wildlife or ships out on the water.
    This lens now means that I have everything from 12mm to 400mm or 560mm with the teleconverter (24mm to 1120mm full-frame equivalent) so nothing is too far away for me to frame properly.
    For its range this lens is neither big nor heavy so my walkabout bag is light and easy to carry all day.

    I looked at this lens many times before ordering but was worried about what reviewers said about it being loose on the camera, in my case this is not true it fits as it should.
    Focus is rapid on my OM 5 ok you need good quality light but images are sharp and stunning, it's quite heavy but the lens shoe fits perfectly on my older Manfrotto tripod which I'm very pleased about.

    All in all it's a good quality lens so as soon as 鶹 dropped the price I got It, not tried with the 1.4 tele yet but looking forward to resuls.
