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: Colours, brightness and quality/price

Cons: for me no one

Opinion: bought it because my canon 17-55 is 2.8 lens was under repair, and it took a long time to get it, needing a similar focal length for a trip I decided on the sigma 17-50 f/2.8 EX DC OS HSM, excellent both as general results of photographs, excellent stabilizer quite fast warm color in shots, Affordable price for such a lens and lighter weight than the Canon 17-55 IS 2.8, although this lens is discontinued and recommended.

Pros: Colors, brightness, price.

Cons: From my point of view nobody, perhaps the hood and plastics, which I would have preferred of higher quality

Opinion: I write this review but I consider myself a simple amateur photographer, so evaluate it in this sense. Bought years ago to replace the 18/55 "standard" at a cost that was, if I remember correctly, of 400/500 euros (new). It has been in the closet for a while also because (read above all) it is a lens for cameras equipped with APS-C sensor. Lately, however, having unworthily equipped myself with a Canon R5, I can use it because the camera adapts automatically, even if in fact it is like having (approximately) a 24/70 but still with f/2.8 aperture. The excursion and movement of the rings is fluid, perhaps a little too braked but I think it's better this way. The plastics are opaque and of not excellent quality but the object, as a whole, conveys a feeling of well-built. One thing that I also found on the 70/200 f/2.8 always Sigma, is the resistance to dust penetration internally. Bright and sharp, I don't think it looks bad on high-end cameras; Using the adapter, it is less unbalanced when mounted on a machine on the tripod, as it is shorter.

Pros: Aperture, Sharpness, Construction, Excellent value for money

Cons: For my use none

Opinion: I took this lens to replace the Canon 18-55 kit. Very apt choice, excellent lens for APSC with 2.8 aperture. AF average, quite noisy but his job does it very well. I found no fault with my use. I would definitely recommend it to upgrade to something more professional after the 18-55 kit. Excellent also the quality / price ratio. If you really had to find a flaw, the hood supplied is a bit plastic.
