I am not disappointed, the quality is satisfying.

I share my impressions after the warranty adjustment. The result has become noticeably better, misses happen, but mostly in poor lighting. It is advised to align with the carcass for best results. I compared the picture with 50mm / 1.8 stm - the fix at 2,8 is noticeably sharper, but it loses in the speed of the focusing motor and the lack of a stabilizer. I think that this Sigma is a good option for the price and picture quality, the main thing is to choose the exact copy.

Pros

1. Constant aperture. At 2.8 sharp in the center, from f4.0 and above - the sharpness is already much better. 2. Fast autofocus performance 3. Convenient fr, allow you to shoot from landscape to portrait, while if you take it as the first lens, it will be easier to understand in the future which focal lengths you need. 4. The stabilizer helps a lot in low light conditions 5. A solid picture at the output, although it is a little "warm" 6. From the aesthetic side - the glass on the carcass looks solid and does not seem like a plug, unlike a whale 7. Price / quality: We look at the price of the original 17-55 f2.8 from Canon and compare with the Sigma. There are no comments here.

Cons

1. The accuracy of the autofocus out of the box. I strongly recommend testing before buying on a special target. My copy was with a terrible back focus on the short end (judging by the reviews, I don’t have one). I gave it for adjustment under warranty - everything was done in 2 weeks, now the focus hits the target much more accurately. 2. Short travel of the focus ring. In my opinion, because of this, it is quite difficult to accurately focus 3. It is impossible to bring the focus manually until you switch the toggle switch to MF 4. Service, or rather its absence. Officials do alignment only in Hong Kong 5. The lenses inside the lens rumble a little, but these are trifles.
