Pros: Price + sharpness/clarity + constant 2.8 min aperture + construction + ease of use.

Cons: None so far.

Opinion: I replaced my Canon 18-55 kit lens with the Sigma. I've been extremely pleased with the lens and the results I'm getting with it. Images have been sharp and clear. I got the lens new from Amazon for $290 USD. I haven't had any problems with focusing or usability of the lens with my Canon 80D. Photos and videos both look great. The construction of the lens is very good. I'm sure this will be my "go-to" lens for a long time.

Pros: Value for money, only paid Euro250 direct from the Australian Sigma importer with 24 months warranty. Silent AF on my copy, Fairly quick AF. Light weight with optical stabilization makes it easy to handle. Handy zoom range. Constant F2.8. Build quality good for the money.

Cons: Nothing for me.

Opinion: Great bang for you buck lens. Formerly owned the Sigma 18-35mm Art and I'd say this is almost as sharp but easier to handle due to the light weight and optical stabilization. Selling this lens as I am also selling my APS-C camera. I can only hope to find a similar quality and great value FX lens like this. Will be missed. From my copy I can thoroughly recommend this lens.

Pros: Sharpness, fixed aperture at f/2.8

Cons: AF "noisy" for videos, rings

Opinion: I switched to the Sigma 17-50 after a year with the "classic" Canon 18-55 and the difference is noticeable, despite the good performance of the lens kit. The fixed aperture at f/2.8 is certainly its strong point and unlike other lenses, it offers excellent sharpness already at TA, which becomes excellent from f/4. Pleasant bokeh, considering the type of lens I would not have expected better. The construction is discreet, the consistency is perceived starting from the weight, adequate for the type of product, while I would have preferred a less contrasted zoom ring also because there is the 17mm manual lock that prevents involuntary extensions, questionable also the ring for the MAF that in addition to not allowing the full-time manual focus, rotates only 45 °, making precision adjustments difficult. The overall yield is excellent but at short focal lengths, in addition to the classic distortion, there is a slight loss of quality on the sides of the frame; on average, chromatic aberrations and stabilization. To conclude, the AF works rather well but in some cases, especially in unfavorable light conditions, it is not very precise; the HSM engine is not particularly noisy, however during video recording it becomes unbearable if you use internal microphones (in this sense the Canon STM, for example, are much better). Despite the flaws, it remains probably the best zoom for APS-C under € 300 and a decent upgrade compared to the lenses in the kit.

Pros: Ta sharpness, construction, MAF speed, stabilization, value for money

Cons: For what it costs, no one.

Opinion: If you wanted to make a comparison with the world of football, paraphrasing even a well-known Ligabue song, I would call this lens an excellent "median": honest, versatile, well done, you mount it, shots and he always gives you a good result ... I had bought it for a use that -- at least reading a lot of reviews -- did little to suit what I would need, "a short zoom" to use under basketball basket, MAF's speed seemed not to be adequate, instead - as usual, I haven't put too much weight on what I read around and when I can, I prefer to buy and try firsthand... - it was enough to mount it on the 7D2 and "as if by enchantment" little Sigma became a splinter, keeping the focus on gusts of 5-7 frames, without any problem. It is already sharp at 2.8, the stabilizer works excellently, the blurry is pleasant although it is not at the levels of the "Hawthorn" IS II (but in my opinion higher than that of the 40 pancakes) and then the construction, even if there is a lot of plastic, is really beautiful, well above the purchase price, the barrel flows smoothly but with the right resistance, so much so that the 17mm lock button I think is superfluous, the lampshed fits perfectly even in the rest position and finally, no problem of F/B focus, consequently no need for fine adjustment (and it is already the third Sigma that does not require "fine af adjustment", I think that in Sigma they have changed something in the "quality control"...)

Pros: Sharpness, brightness, construction, value for money.

Cons: Autofocus ghiera.

Opinion: I have owned it for almost a year now and I am very happy with the purchase. It is built well and in hand by a beautiful feeling of solidity and in the packaging there is a very useful semi-rigid handbag for transport. The sharpness is great at full opening, which is great news for taking photos with poor light and getting photos with a nice blur. The stabilizer is effective and not by any kind of problem. In the end it became the lens I use most often. The only flaw I found him is the MaF ring, which has a really, really small run and in a position that too often ends up under the fingers getting stuck and thus preventing the operation of the Af.
