Pros: Quite Sharp, constant F2.8 aperture, build quality if compared to kit zooms

Cons: I did not like the colours, AF is not the fastest, no stabilizer

Opinion: I bought it long ago with the intention to replace both a Canon 18-55 IS and a 50 mm F1.8 prime in one lens. Although its sharpness was better than that of the 18-55 mm IS at the same apertures and similar to the 50 mm prime at F4 and above it never became one of my favourite lenses. Colours were to cool and lifeless for my taste, AF was a bit slow and noisy. Other than that it had a nice build quality and gave no reasons to complain. I nevertheless sold it again and kept the prime and 18-55 IS, because the stabilizer was more helpful than one or two stops aperture for static objects and I preferred the character of the prime for shooting people. Today I would probably buy a Tamron 17-50 F2.8 VC to have the best of both worlds (then it was quite expensive).

Pros: Cost in Used, Focal Range, Constant 2.8, Weight, Macro

Cons: Construction, sharpness from f/4 down, slow and noisy, sometimes inaccurate autofocus. Unusable in low light.

Opinion: Taken to replace the 18-55 kit on my Canon 70D. For a novice photographer it is a good lens, especially if we consider the fact that you can now find even under 250, which for a standard 2.8 lens for aps-c is a great price. In addition, the size and weight are quite small. The strengths, however, end there. In my opinion, this is not a lens that can be used at a professional level due to the outdated, slow, noisy and inaccurate autofocus, especially in low light. Not very good sharpness below average apertures. The build isn't that of high-end lenses, and it doesn't feel like you're holding a particularly solid lens. The macro function is good and allows you to take home pretty photos.

Pros: Good lens to replace the kit one. Good brightness at all focal lengths Robust construction

Cons: It's a bit poor in backlight, not very precise and noisy focus, barrel distortion especially at the minimum focal length

Opinion: I've owned it for many years now and it still does its job with my dated Canon EOS 50D, which is also very old but for now I wouldn't replace it with the new Canon M system that still doesn't convince me. It is a very good lens both for its brightness at all focal lengths, and for its versatility on almost all occasions. It's sharp and quite defined throughout the frame, although in my opinion it looks much better at medium apertures, especially between f/4.0 and f/8, A f/2.8 has a really nice blur and therefore suitable for portraits. It gave me some problems in backlighting, but not being very fond of this type of photography, it is certainly my fault. Don't expect high performance on the autofocus, as the lens is not ultrasonic, the slow speed and noise are noticeable. The front lens is quite exposed. It must therefore be protected to avoid scratches or worse, better with a rigid lens hood, especially if those like me who do not like to add other glass in front of the lens such as UV filters etc. I recommend it both for the price, and for the fact that when compared to the kit lenses it is definitely the top (even if the kit lenses should not even be compared to certain lenses)

Pros: Construction,Robustness,definition,general yield,constant opening f2.8,blurred pleasant.

Cons: On some occasions, there is little resistance to backlights. Focus a little noisy. Focus that rotates in AF.

Opinion: Optical taken for "two lire" to be mounted on a Pentax K3. I didn't expect much, given the age of the project and knowing the past Sigma reliability. Well... I soon had to think again!! Used on a number of occasions and, really, never let me down. Almost certainly, I was lucky with this specimen,but the sharpness, the definition on the whole frame (even at TA), is really remarkable. The ACs, there are, but they're correctable. An 18mm hair of distortion, but nothing dramatic or unrecoverable. The zoom dial flows smoothly, without hinting. In landscape photos, it behaves well from f4 onwards. In portraits, 2.8 is really SUPERB. Details in large quantities and a really nice detachment of the floors. Generally, in the backlights, it does not create problems (I love to take portraits in the light of sunset), but I happened to take some landscape photos at a sunset and I noticed that in some image, or rather, in some angle, a very bad reflection appears impossible to correct. But given the age of the project and the cost, I think it's more than acceptable to have some compromise. The focus, well... it does not have an AF engine, so its speed and partly its silence, depend on the reflex on which it is used. Pentax, you know, certainly doesn't shine on the AF side, yet it's quite quiet and precise on all occasions. Even the most difficult ones, like a backlight or the like. On average, the percentage of shots lost is 2%. Like the other photographic systems I had previously (Canon,Nikon,Fuji) and used in a very similar way. The construction, it's solid. Robust. The only negative note,is the opaque coating,which personally, I do not like very much; gives me the impression that it "attracts" the dust. But maybe it's just suggestion. The weight, of course, is compared (for example) to a Fuji 18-55 2.8-4. But we're looking at a zoom optics f2.8 FIXED... Many builders don't know how to do much better. I mean, dated optics, sure. But definitely valid to replace the classic kit lens... and make an abysmal leap in quality, because with kit optics, nothing has to be shared (if not focal), as it is much superior. He plays it quietly with more emlasic optics. Honest dimensions; he's fine on a slad. Beautiful to see,fluid ghiere, great sharpness,blurred pleasant.... for that little money it costs, to have absolutely!!

Pros: Brightness, robustness

Cons: Focusing on low light difficulty (coupled with external flash), failure to stabilize

Opinion: I have this lens for more than a year and with the passing of days I'm getting more and more defects. By doing a substantial use with low light the shutter 8 times out of 10 is out of focus. Instead, for optimal light conditions it is also great at maximum aperture and the focus though not being ultrasonic is very accurate. Recommended for those looking for an economical substitute for the base kit.
