The lens I use with the D800 is good, especially considering that it is not expensive. It shows itself well with aperture 5.6, sharpness will be better than that of 85 1.4 (Even many Internet resources write about this, otherwise, of course, it will be inferior to 85)), and with such aperture 5.6 focus works well. The lens is much better than Canon's 50 1.4, but Canon has 1.2 which gives it a big + I would like Nikon to make 50 with a gold ring and fix all the problems, let it be more expensive, but it will not affect the frames. Whoever thinks about taking it, I advise you to take a good price, I compared it with the "D" version and liked it more with the sigma, although the sigma on the open hole in the center will be a little less common and on the sides it will be soapier. score 4/5 (Autofocus still kills in some conditions)
