Man, after using the Datacolor LensCal to try to fine tune the AF micro-adjustment for my new Sigma 105mm f/2.8 Macro HSM on my a7R+LA-Ea4 adapter, I cannot get the lens to hit sharp focus on the target at a consistent basis. The most success is around +8 to +11, but sometimes itll still front focus, other times itll back focus, and sometimes itll be spot on. Anyone having issues hitting critical focus wide open with either a Sigma lens or the LA-EA4 adapter?
