Pls tell the difference between Sigma 17-70 f2.8-4 (old version) and new version with C on the side, focusing on image quality and performance. Is the new good at f4 like the old one. Thank you so much.

pulsar123 Goldmember More info | Mar 31, 2013 09:07 | #3 I compared MTF plots for both versions, and they looked comparable. So I don't expect the new version to have better IQ. Other things, like AF accuracy, might have improved. 6D (normal), 6D (full spectrum), Tamron 24-70 f2.8 VC, 135L, 70-200 f4L, 50mm f1.8 STM, Samyang 8mm fisheye, home studio, Fast Stacker
