Tamron 100-400mm f/4.5-6.3 VC USD - Is it any good on the Canon EOS R6? 

I have the same combo but the IQ deteriorates badly at 400 MM especially during the birding. I tried with an R6 Mark II with same result. I tried it with an older full frame Canon camera and the images were very sharp. The camera with its kit lens (18-135) gives me really sharp images (Even through a glass door). I can't figure out how to fix the issue.. took it multiple service centers but no luck. Would you have any suggestions? Would be great if you could share your thoughts. :)

@@incorrigiblesam After having Tamron 100-400 for over two to three weeks I returned it. It was fine with stationary subjects, but not good with birds in flight. I bought a Sigma 100-400 that woks very well Recommended.

Definitely a great lens for the Canon R6. Although, if you want to go native, I believe canon has come out with a similar 100-400 mm RF lens at a similar price range.

@Alex Matute I don't mind adapting since all my current lenses are EF. Also, the Tamron is sealed, better build, and faster. New it costs more, but I'm getting it second hand for the price of RF, so it was a no brainer.

@@alexmatute5228 Cheaper actually

Appreciate it! Havent had time to create another video lately, been busy with work, but will try to make a review of the sigma Sport 70-200 f2.8 with my R6 soon.

Thank you. My two previous cameras were the canon SL2 and the Lumix g9 with attached canon lenses, that is why my R6 has felt like a dream with its amazing autofocus. I'm sure the R5c is an amazing camera! Congrats on the upgrade!

I was in the same boat before purchasing this lens. I ended up going with the Tamron due to its waterproofing and lightness. Sigma is also a great choice but I think its a bit more expensive.

yes it does.

@@alexmatute5228 thanks for the answer! It was the only thing stopping me from buying one: the green "fps+" mark 😀

Yes

it works perfect with the R7. I have a video on it. Check it out on the channel.

TQvm for the reply...I ll check it out.. thanks Buddy 🙏🤟

Yes, If the T7 has a little red dot on the lens mount then it will work with it as well.

I do not experience that issue. Have you tried back button focus? Also make sure that your animal eye detection focus setting is enabled.

@@alexmatute5228 The answer to both is yes (back button and animal detection). Further even when photographing non-moving objects, I have found the need to adjust the focus ring to fine tune the focus. I also set with the Tap In Console to the default settings and took any firmware updates.

@@mikeklubok7270 in that case, I dont know what could be going on. I have not had that issue with my copy of the lens. One option would be to rent the same lens for a few days and see if you run into the same issue. If you do, then you can send your copy for a repair.

yes it is!
