The Sigma 85mm DG HSM was my favorite lens on my Canon 5D mkIV. I switched systems and got this newer version and ai have to admit it is much better in almost every way. It is smaller, lighter, quieter, faster, and has better features. It does have more vignetting and pin cushion distortion , but that can be corrected easily.
This is an amazing lens and an amazing value! The professional reviews are correct, it is as good or better than some other great 85 and 90mm lenses. On my Leica SL2 it compares very well to Leica SL lenses and that is saying something!
