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.

Pros: Good build quality from f.9 is perfect to f2.8 is good, even at night

Cons: focus ring is difficult to operate, the rest is a great lens to replace the kit

Opinion: I took this view for two months and I must say it is a good quality lens, I replaced the 18-55 kits, the difference is more accurate af, at f2.8 allows fuzzy good night behaves well, neutral color, it offers a nice yield from f.9 already, I recommend it as a first lens in place of the kit is located at good prices.

Pros: robust, good quality if prepunched (f 8-11), the overall yield acceptable to f2.8.

Cons: distortion "barrel" very obvious focal length 18, is corrected only in PP, there is the possibility to correct the focus manually while in AF, (the ring is locked), AF slow (non-USM).

Opinion: I have this light for 6 years and use it regularly, is solid and robust as Sigma has accustomed us. Good overall performance for sharpness at f2.8 at all focal lengths, even the good macro. Unfortunately, at least my copy, has back focus problems with my 30D, Canon unsolved problem from assistance that does not even come into the lab Canon lenses do not, I'll keep that. Aberration decided to "barrel" to the focal length 18, which decreases as you go up the focal impractical for photos of architecture and interiors, autofocus is not fast and noisy, due to the fact that it is not USM.rnSostanzialmente good alternative to the kit plasticone , at least it was in production until, well as a handyman and reportage, good for portraiture.

Pros: brightness and sharpness

Cons: front lens against dust too exposed to the impact and scratches

Opinion: goal is a relatively inexpensive but quality ', the images are very sharp at all focal lengths f 2.8 even while there is some reflection in the light, partially solved with the lens hood supplied with the lens front is a bit exposed to shock and scratches therefore recommend a filter uv permanently mounted Great price performance
