If you are talking about moving, handheld shots, focusing at 400mm is not easy. The focus ring does not extend with the lens, so things get off balance. On a tripod, the focusing at 18 or 400mm are pretty much the same. I've not really noticed any difference in AF with this lens between wide and long shots. Thanks for the comment. :)
I should have been more precise. It's about tracking/focusing objects while shooting a video. Currently I have a 700d with that tamron 18-400 and while in terms of photos it is sufficient, I will do the rest using AI and Photoshop, in terms of video AF works terribly, especially in live view
@@m3ntorpl I would say so-so. It tracks alright as long as there is contrast. But I can't say if it is the 90D or the Tamron that makes it okay. I also do not do a lot of continuous focusing/tracking shots. Thanks.
Thanks for watching. :)
Nice video, Sean.
Thanks. :)
How it is going with focusing on 400mm on moving objects like vehicles?
