any opinions on this lens for motocross photography?
fast autofocus? good lens?
thanks
Researched this quite a bit last week - sharpest at 70mm, somewhat soft at 200mm. Prone to front focusing I think.
I've got the MK I & I'm very happy with it
The majority of this lot were taken using a 30D with the Sigma.
It's just a straight dump from the card without throwing away the junk or any tweaking so should give you an idea of the hit-rate![]()
Yep, fast autofocus, some softness issues but generally ok, on the expensive side if you're not going to use it much.
