Great lens for crop. But when buying, be careful, you can’t rely on quality without looking, after all, it’s not L! With its pros. Constant decent aperture, ultrasonic motor, stabilizer - all this is very useful, especially if you sometimes indulge in shooting video. Internal focusing, the location of the rings for focus and zoom - everything is convenient. Its cons: The quality can vary greatly from one copy to another. I chose from two brought to me in the store. One turned out to be decent, and the second has dust between the lenses, back focus and a noticeably smaller depth of field.
