For the money, a very affordable and good lens, especially for beginners and amateurs, its counterparts from other companies are many times more expensive, and only pros will probably see the difference in photo quality. Its pros: Very cheap, light, fast, fast in aiming The pattern on the open aperture is soft, pleasant bokeh. On a more closed one, it is sharp enough. Different cons: Sometimes smears on a very open aperture. Noisy during autofocus, which is somewhat undesirable for video. Chromatic aberrations are noticeable, where would we be without them, plus, due to the small number of aperture blades, bokeh, when closed, gradually becomes not a circle, but a nut. However, with such a price-quality ratio, these are rather trifles.
