I bought the sigma 35 a year back, after reading many reviews that the AF is far more consistent than it was in the past.
fast forward to today, i still get quite a bit of OOF shots with the sigma as compared to my canon 24-70ii. The keeper rate is probably around 70% vs 95% (if we only take into account the aspect of nailed focus).
does anyone else face the same sentiments as i do? sure, it's not an apple to apple comparison, but i have this feeling that even shooting the sigma @ 2.8 doesn't give me consistent AF as compared to the canon.
all comments welcome!
Remove the "feeling" and simply do a real world test.
Set the Sigma to F2.8, same settings for everything as the Canon lens. Shoot at the same focal length, 35mm. Set up on a tripod. Set up a dummy some where to test shoot. Nothing moves. Use a remote shutter release. Do a series of 100 shots on each lens. Then see which nails focus, and which does not. Count them up.
I have a feeling that you're just missing focus at F1.4 handheld. And if you're missing at F2.8, it's more due to your handholding technique or typical body sway than anything.
