There might be a back-focus problem with ur lens? Especially if you are shooting very wide, like F1.4..
My 50mm F1.4 has a slight backfocus problem i.e. when i shoot wide open at someone's face and focus at the nose, a lot of the time the ears wud be sharpest, heheheh
EDIT: lol same timing we post
use a focusing chart to test if your lens is suffering from front/back focusing or not as it will be more accurate.My 50mm F1.4 has a slight backfocus problem i.e. when i shoot wide open at someone's face and focus at the nose, a lot of the time the ears wud be sharpest, heheheh
EDIT: lol same timing we post
the AF might mis-focused sometimes due to the fact that the AF covers a large area (esp when u are focusing on a small piece of subject)...front/ back focusing will be more prominent when you are using the widest aperture and for this case f/1.4....
get ur lens fixed if it has the problem, else it will be very annoying..isnt it?

Wow, that's cheap. I would get a 2470 before 70200. Sigma HSM 2470 looks promising also

A dedicated camcorder will do. Would you carry a 1.5kg camera for video shooting?
My hands and arms are refusing to do so.
some may say the quality sux and this and that, but as said it is a BONUS to have that feature QUOTE(hanafinoor @ Sep 4 2009, 05:12 AM)
sigma HSM 2470 - had it before ...so many issues especially gear stripping. Wont recomment that.
AFAIK, sigma 24-70 DG EX has gear stripping problems on alpha but I tot that HSM will prevent that problem happening...Yes?No?
