For a long time the Sigma 35A has been one of my favorites. With the transition to the Sony A7RM3, I was faced with the choice of taking the 35A DG DN or 35GM. In the end, GM won more because of the weight and size, I need to fit into a small shoulder bag that I carry with me all day. Initially, I liked the Sigma picture more, but after comparing, I realized that the differences for me are minimal. Sony has slightly higher contrast. But the contrast of the blurred background is also higher, which sometimes works in the negative compared to Sigma. It should be noted that the comparison is not entirely correct, the old Art on Canon 6DM2 is compared with the new lens on Sony). On the net you can find a more correct comparison of 35A DG DN with 35GM.
