High-quality equipment in general, inspires, I want to take my camera with me everywhere. The whale has now completely become unnecessary, the yongnuo 35mm f 2.0 and this lens are enough for me. I took a used copy - it cost half the price, which I am quite satisfied with. Got pros: I will note that it is a pleasure to shoot in the evening, in low light - a really fast lens, sharp at maximum aperture. Fairly wide angle. A very compact lens, after it you just don’t want to cling to others) Cons below: focusing is not as fast as it seemed, in dark scenes it is dull just like lenses with a conventional motor.
