Pros: Constructive quality, acceptable price

Cons: in my opinion too "soft"

Opinion: I bought used this lens and used it on sony alpha 55; I was attracted to the affordable price and compatible with my budget (about € 200) for a 2.8 in that focal length. The main gap that led me to sell the lens was the lack of definition, especially 2.8. The reason I did was that if I have to have a 2.8 and to enjoy it I have to close at least two or three stops ... I'm losing it. For the rest I have nothing to say since weight is a parameter that you he knows it right away; if you accept it well, otherwise it is useless to buy it then complain. I conclude by saying that I am not a lover of post production and so I can not tell if we can get improvements in the white room.rn

Pros: Relatively low cost in comparison to the equivalent Nikkor, weight, 77mm filters, brightness, rings comfortable, build quality, focus ring one touch

Cons: Sharpness wide open, fast autofocus, zoom, front end too

Opinion: The build quality of my copy is great, I talk about the EX version with the slide on the scale of meter / foot. The ring focus can be moved axially by selecting the AF mode or M, which is convenient to not have to waste time moving the switch on the equipment and start right from the beginning to focuse on hand (or vice versa). The focus (on the D90) is quite slow, at least noisy, but accurate. The optical quality does not come close to that of the unmatched Nikkor AF-S 28-70 2.8, and is soft wide open most of the frame. Already a closing stop the situation improves noticeably to reach a high quality 5.6 aperture. The filters 77 are among the pros because the majority of the optical high-end 77 has a diameter, so it's pretty standard. The weight is enough to content. The finish of the Sigma EX series is gradually discard, but I personally do not happen, I think it depends on the conditions in cui works the camera, and having never stressed, never had a problem with the posting of the exterior trim. The petal-type hood is comfortable and functional. The built-in flash can not be used to below 50 mm because otherwise comes to create a shadow due to the elongation of the front group, which has an excessive stroke. I used this lens for three years, and I replaced it recently with the 24 2.8 AF-D, simply because I realized that I used almost exclusively to 28 mm. I recommend it to those who can not afford more expensive solutions but do not want to give up a lens to medium-high 2.8 diaphragm.
