Cons: I find the focal range awkward.
Pros: Good optics even wide open.
Summary: I got this lens because I was blown away by its big brother, the Sigma 50-100 f/1.8. But this lens is much less attractive to me. First, the wonderful OOF effects that the longer lens achieves effortlessly are hard to achieve with the short focal lengths of this lens. Second the IQ is lower than on its big brother. And finally, the focal range just doesn\'t fit my shooting style -- I often want more reach than this lens provides. So I find myself using the Nikon 17-55 f/2.8, which is marginally worse optically but much more congenial in terms of focal range.

Cons: A touch heavy Shortish zoom range
Pros: Excellent sharpness Good bokeh Nice colors and contrast
Summary: For me it focusses very well on all focus points on my Nikon D500 and D7500. No focus issues at all.

Cons: Size. Weight. *Autofocus*.
Pros: Optics
Summary: The AF on this lens is broken. Sure, you can fine-tune the AF to give very sharp results when using the central AF point. But it consistently front-focuses whenever you use lateral AF points (Nikon D7500 here, but it was reported also on Canon), and by a wide margin. If you like out-of-focus faces and sharp cuffs, this lens is for you. Now if you want to enjoy its sharpness, then it\'s contrast detection or manual focus with Live View. Not for me (too slow). Focus-and-recompose means trading off timing for focus, and with a stunning 51-point AF module on my body, this won\'t be my choice either. The lens went back to the store.

Cons: The weight, I guess.
Pros: Everything but the weight.
Summary: I never thought I'd experience a lens like this in my lifetime. I've been shooting seriously for 50 years, much of it on Leica M and Nikon gear. I've never seen resolution, microcontrast and colour like this. I'm pretty sure it outdoes my favourite Leica M lenses - the 28 and 35 Summicron ASPH,lenses and definitely the 50 Summicron. Stunning.

Cons: Slow focus (but for an 18-35mm f1.8 which i do not intend to use for sports, it's OK), CA (but as I shoot raw, no problem in post processing), weight (again, it's an f1.8 lens, it simply can't be that lightweight) Focusing on SLR (those with that clapping mirror) is inaccurate, not correctable with Sigma's docking station
Pros: fast/bright lens, very sharp, great built quality, nice bokeh AF on mirror-less cameras (with LA EA3 on the A6300, BUT only in AF-C mode) is very reliable, even in dim light (with the iris open)
Summary: I bought this lens for my A77 and was very disappointed 'cause the AF was very unreliable, OK for people, but horrible for landscape. Tried to fix it with the Sigma docking station, but that only works if you have a clear front- or back-focus on the lens and you don't have the possibility to correct it by micro AF adjustment. This lens let the AF systems of the camera (A77/A58/A55) hunt for focus, but almost never nailed it right, in manual mode, excellent sharpness from corner to corner, in AF mode horrible. Since I now own a A6300, I'm really happy with this lens, with the AF sensors right on the image-sensor, focusing is really great, but only in AF-C mode (AF-S is still not the best, center OK, corners soft, while in AF-C also the corners are sharp, strange but my observation), and even in very dim light the lens focuses reliable. So in my opinion a great lens in combination with a mirror-less camera, on SLR's it's mostly not a happy-maker.

Cons: 1.Very slow autofocus, sometimes very accurate, but most of the times no focus at all (and I know how to use it believe me). It's very bad in poor light, hard to acquire focus and when it do acquire it will be wrong focus. It maybe can be corrected with sigma dock but it is still slow and hard to acquire. 2. I can see pixels.
Pros: Color is better then Nikon 18-105 and thats all. And it has classy look, nothing more.
Summary: I comparison with 18-105, Nikon is faster to acquire focus and it is sharp always. On 300 fotos 1 is a miss. Sigma miss 40-60% photos. If you shoot lowlight or some parties, don't buy this lens. With Sigma, picture is build with sharp visible pixels, Nikon has smoot transitions so the face of the person looks more natural. Tested on Nikon D7100.

Cons: Big and heavy, but understandable for 1.8.
Pros: Image quality excellent, equal or better than prime lenses. Good for a lot of situations. Excellent in low light.
Summary: It is a very good lens, but less useful than expected. The short zoom range does not allow to take it as single lens for any trip, as one usually needs both wider and longer as well. To take it with many other lenses makes the bag too heavy. Excellent for use at home.

Cons: Weak focus on my copy of 7D. Sometimes deadly accurate, sometimes no focus at all.
Pros: Near perfect glass. Image quality is superb, and not just in terms of sharpness. The lens imparts a special quality beyond sharpness.
Summary: I have heard that Sigma "corrected" its focus tolerances - great for those that are entering the fray in the "post-correction" era. As for me; I'll manual focus as that's what I'm used to. My assessment of build quality is based upon the problem with auto-focus and I'm being generous reluctantly. I recommend Sigma, but with a strong emphasis on the user approaching Sigma as a manual focus lens-maker...imaging of the highest caliber indeed.

Pros: Super sharp. A fast zoom at this price!
Summary: A bit of an odd zoom range, but it works. Sharp and fast , mounted on a 60d it's been a great indoor lens. Used outside it can give you some nice landscape perspectives and street shots.
