I am doing bird photography. I am very happy with my Canon EF 400mm f4 DO IS ii in combination with Extender EF 1.4x iii and EF 2x iii. I am considering an upgrade of my Canon 7D ii and see only the Canon R5 as an upgrade option. My question is if anyone has experience or has read about others' experiences with the combination R5 and EF 400mm f4 DO IS ii. I am particularly interested in autofocus and tracking with Extender EF 1.4x iii and EF 2x iii. I also have a question about the R5...

Hi, I'm a hobbyist photographer at max and trying my hands in BIF. I have EOS RP body and 100-400 MK II lens with couple of extenders for this job. I'm not happy with the AF tracking and high ISO performance of my RP. Also can't get the APS-C reach. So wondering to buy another APS-C body. Undoubtedly 7D MK II is highly recommended when it come to action shooting. But my question is that it is worth to buy this aging camera in 2020? I'm considering used version.  It seems clear that Canon is...

Hi! I tested last week a 2x extender on my 6D + 70-200II. while at 70/140mm the results were quite good, at 200/400mm I noticed afterwards a slight front focus issue. So here's my question: can I MFA the 6D with 70-200II + Extender without affecting my settings for the 70-200II alone, or in other words, does it allow a dedicated adjustment for lens + extender? I can't find the info in the manual. Thanks in advance!

I have Sony Cyber-shot DSC-RX10 III. I love point shoot cams because it is easy to use. I am panning to change my way to Canon EOS R :) I have no idea how to create a set. I took school kids photos and swimming and football and indoor events etc. I like action pics. I will need adopter also :) Canon Mount Adapter EF-EOS R Canon Control Ring Mount Adapter EF-EOS R Canon Drop-in Filter Mount Adapter EF-EOS R :-)As a lens I like : Canon - EF 70-200mm f/2.8L IS III USM Canon - EF 28–300mm...

I read that people are using the newest 600mm from Canon with the 1.4x III extender because this combination is sharper as the newest 800mm alone. Is this true? What about autofocus? I own the newest 400mm from Canon, so I am wondering about the same questions with the 2.0x III extender.

I am thinking about buying one of the Canon extenders for use on my 6D/EF 70-300 f/4-5.6L combination. I have read a number of reviews that suggest the 1.4x III is sharper than the 2.0x III, but before I take the plunge, I would be grateful for the observations of the forum please. I want to extend the range of my telephoto for some wildlife shots I want to take, and see the extenders as being a more affordable option to the purchase of a new lens Thanks Geoff

Hi. I just bought (almost) new Canon EF 100-400mm lens for bird photography for my 70D camera. As I already own an old Voigtlander Ultron 100-400mm I know that such reach (even with the camera's 1.6 crop factor) is sometimes not enough and I am not that much into photo-cropping in PP. I was reading many threads for last days - unfortunately all of them very outdated - about Canon's 100-400 L + TC setup (mostly with 5DmkIII or 1Ds) and read a lot about the problems with autofocus etc. My...

I have a Canon EOS 6D FF camera and I am going to buy Canon EF 70-200mm f/2.8L IS II USM in the near future. And while 70-200mm would cover most of my needs when it comes to reach, I do think of getting more reach for occasional use. So I think of Canon Extender 1.4x and 2.0x (version 3) or a Canon EOS 70D which will give the 1.6x factor. With teleconverters I'll get 280mm and 400mm but with cost of the IQ, focus speed and aperture, with the crop camera I will get 320mm but of the cost of the...

I am presently in the market for my first L lens. I am looking to get a telephoto lens that can get me to 400mm, and potentially beyond, for wildlife photography, mostly birds. I was convinced that the lens I was looking for was the 100-400mm f/4.5-5.6 because of the l-series build and image quality, and because of the IS. I have also heard good things about the focal range that the lens possesses "saving the day" for some, but I also have my concerns about the lens. I like to manually focus...
