| p.1 #13 · Sigma Optimization Pro v1.1 with Lens firmware updates |
In general I'm very happy with the AF accuracy of my 35mm copy. Well, once taken into account the huge size of the central AF point in the 6D, which may cover too many subjects on "distant" targets (and not necessarily locking in the nearest). Maybe the 5D3 would be "better" on this respect. In fact, the outer points, despite less capable, seem more accurate with far subjects, and this includes very well isolated targets (as a full moon, for example; I'll post later a few pics).
I just have ordered the dock mainly to have the latest firmware, not because any problem with the lens, which is awesome. BTW, I laughed at Sigma reasoning for the update, but later I do noticed a taste of abnormal sounds one time, in a silent enough environment, so they certainly may occur (have been unable to intentionally reproduce them later, though).
I have a question for those who have updated: have you noticed a change?. Do you find your lens equal, better or worse after the update?.
One more question... as everybody could expect from a software developer, I'm wary about software updates . Does somebody know if it possible to downgrade to a previous firmware version using the Sigma update software?
