I remember borrowing a friend's 50mm 1.4 Sigma ART half a year ago and I just fell in love with the capabilities of this lens and a month ago finally I was able to pick it up. The sharpness is just incredible for this price. I use it with my A7Rii so my shots get quite detailed. The lens produces a very nice bokeh. They are well defocused and have a nice round shape. The autofocus isn't too bad but I don't care, I bought this lens for the sharpness of my images. The lens is quite heavy and large. But I don't mind. The workmanship is good, I like the design. While I would like the focus ring to rotate more smoothly, it's not as smooth as the focus ring on my Sony FE 24-105 F/4 G OSSA. and for the price (which, by the way, is more than $200 cheaper than the B&H). This lens gets 5 stars from me.
