I shoot full frame. It is probably biased to judge this model if I came across a good copy. Before buying, I looked at comparisons with kenon 1.8, test shots, read reviews, but mine actually turned out to be better: a bit to add sharpness to the picture programmatically - an excellent shot, at an open aperture, sharpness, etc., at the level of a closed aperture. I once had a canon 1.4: on apertures up to 2.0 there was soap on light sources, but this one does not have such soap. Autofocus doesn't seem to work. But my copy is probably an exception. The only impression with such materials and backlash is that it will fall apart at any moment)) I took it on Ali for 2800r. I am personally very pleased. took exclusively for video (shortfilms to shoot)
