I have just watched/read a few videos/articles where people said how this particular lens wasn't sharp on an APS-C sensor at all.
Does anyone here have such combination and can comment on the sharpness?

I plan to grab the lens off someone tomorrow, it's in a mint condition, but if it wouldn't perform too well on my 80D, I might be better off not buying a telephoto at all.

I used this lens extensively on 70D and I think 80D. It worked fine. Focus was snappy and acccurate (better than the sigma and tamron 100-400 which I also owned ). It was sharp.
