I don't know. It does seem odd.
I found that consistency was definitely better than the Canon when focusing at low light in FoCal, but mine has a clear issue at distance and I've now contacted Sigma to ask them for their view.
I really want to like this lens. It is clearly producing more consistent results at certain light levels and distances, but before I'm sure I need a copy which is properly set up.
It's sad since Sigma are clearly rockin' it for optics, but they're not for AF. My Canon 24-70 V2 that I got was bang on and always is and always has been. Best performing lens I've got in many ways, so I do think Canon can do it, when they want to....Show more →
Have you used the dock to calibrate yours yet? It seems that once people sort this the lens is fine.
Just to clarify my issue; I use the outer AF points a lot, and as the light levels drop my ability to use these points does reduce (with all lenses). With the Sigma this happens earlier than with the 35L. The Sigma 50 also let's me use the outer points in lower light than I can with the 35. AF performance is great apart from that.
