Hi All
I've read the reviews and I know about Sigma's well-documented AF inconsistencies, but what are these things like to live with?
I've recently sold my 85mm f1.2L II as I was offered a very keen price, and while I appreciate it's a true artist lens I just got sick of the lateral CA issues when newer designs such as the Sigma Art, Zeiss Milvus and Samyang XP offer up better performance at a marginally smaller aperture. I'm tempted by the Sigma design as it's received many positive reviews, and even if the AF lacks consistency at least it's an option that the Samyang and Zeiss designs don't offer.
I'm sure the Canon fanboys will say the f1.2L II can't be touched but (and in spite of me being Canon-loyal) I've had my time with it and found its limitations. The f1.2 aperture is nice - and unique for an 85mm AF lens - but I can live with f1.4 quite easily for all the potential benefits offered.
One very specific question, on the subject of AF inaccuracy with Sigma's reverse-engineered AF algorithms, does this issue still manifest when using live view or is it restricted to phase-detect AF? I generally used the Canon on a tripod using live view, manually checking the focus was where I needed it to be (and for all those people who praise the Canon it could and would miss focus on occasion with PDAF, necessitating LV for critical images).
Just to be clear, I'm only interested in hearing opinions from Sigma owners as this is the lens that looks to fit my needs - if it's not a dog to live with of course...
Cheers, Darkly
