I shoot on 200D Everything about this lens is good. To tears, I want a little more aperture. But if he had a constant F / 4, it would be L-ka. 250mm on the crop is power. For such a price, there is no way to achieve such an approximation on the FF. The lens gives opportunities. To say that this is a wonderful device is to say nothing. This is my favorite lens, I love it more than my life. (only at the time of publication I noticed that the photos are too compressed, of course, everything is noticeably better in 6000x4000)
