Bought it for video. We needed a wide angle and aperture ratio. Now about Autofocus. AF can try to focus on the face several times, all with hellish noise and eventually fail (most of the video is a little out of focus despite focusing on the face, for example. I’m generally silent about tracking AF, it’s completely dark there). At least 250d. Different pros: Price, but on the secondary market you can buy a little more expensive much more interesting option. Passed this one and bought a sigma. Cons: 1. HORRIBLE ASSEMBLY. 2. Very noisy autofocus. 3. Yes, and the autofocus itself is so-so, but it would not even be a particularly minus, but the travel of the manual focus ring is very small, which makes focusing difficult even in manual mode. 4. Sharpness, chromatic aberration, vignetting, all this is there, but in general, not everything is so scary.
