Hi Mjh1, How does the autofocus compare with the RF100-500? Thanks

Thank you very much. I think I will keep the 5DIV for now.

Hi Kent, that's not possible.

Thanks for your reply, Michael. I am considering the 90D due to its large pixel density. Do you have any thoughts regarding AF on the 90D?

Hello, I'm new to Canon and recently purchased a 5D MK IV to pair with a sigma 500mm f4 S. I also acquired a 1.4 teleconverter. I take photos of wildlife and while I find the camera to work quite ...

Thank you Stan. We had a good return experience with E-infinity. We are considering purchasing a 70-350 again. Thanks, Tiago

The same birds on the same tree under the same light and with the same settings The 70-350 was failing dramatically in that situation but also in other much more basic situations. As per original ...

Update: Just tried the same (a6400) camera with a Sigma 500mm f4 S + 1.4TC + MC11 and didn't have any back focusing problems.

I understand your explanation but completely disagree that what we were seing is perfectly normal. Our further tests demonstrate otherwise. I used to have a 150-600mm f6.3 on a D7500 (both with ...

Thanks for the tip, Geffen. We also tend not to use UV filters. We think there was a fault with the lens and have returned it. Luckily the people at E-infinity dealt with the return quite well.

Thanks for sharing your settings Angelus! We're also quite seasoned photographers.

Thank you Martin. We tried different settings but it didn't help. We have returned the lens and whenever we purchase a new one we hope the problem won't persit.

Thanks for testing

I just did additional testing: CONDITIONS: I placed 5 seeds on top of a white surface, placed a video light next to them, placed the camera on a tripod (beyond MFD) and tried focusing on the ...

Thanks for the reply. My partner has been shooting in AF-C with small focus point area and real time tracking. Regardless of high shutter speed and iso, it's clear the images are back-focused. We ...

Thanks for your replies! The equipment was purchased from E-infinity and I suspect they make it harder to return and to ask for a replacement, lets see... I will attached some photos here for ...

Hello, My partner recently acquired a brand new a6400 and 70-350mm for taking photos of wildlife. We are experiencing extreme focus inaccuracy with the combination. We have tried a variety of ...

Thank you. Hopefully the experience with an A7 III will be similar, especially with the most recent firmware updates. A while ago Dustin Abbott reported tracking with the A9 doesn't always work in ...

Thanks. As strange as it sounds, I'm confident their article is not accurate. I think they claim incompatibility so that they can avoid responsability for problems that may arise. Many reviewers ...
