Hi, I have just bought this lens and found the same issue. I correct in camera for front focus but then a distant shot shows real softness. Remove the adjustment and the distance is fine. Stopping down to f4 takes the problem away.

I assume you were shooting at 1.4?

Hey dude, you need to get the Sigma dock. This is because the dock will give you 4 distance categories to microadjust. Having only 1 value to microadjust is not enough because the 35A is not calibrated to focus consistently at all distances. Also, the 35A's 4th category, the infinity zone, is a little tricky to calibrate. See my past comments on this quirk...

Yes I was using f/1.4.
