Pros: sharpness, speed, detail, f: 2.8, lightness

Cons: only serves to cameras with aps-c sensor, could be firmer in the front segment (fluctuates a bit when in 55mm)

Opinion: this is my lens of choice for travel photos, portraits, nocturnal, architecture, for any service. Mounted on my Canon EOS 50D produces a set of very high quality and performance. The only thing it lacks to be an L series lens is the red stripe, but also did not make sense to Canon to produce an EF-s series lens as a L series. In all the features it provides the lens-end to users of sensor APS-C.

Pros: Opening, quick focus.

Cons: Although well built, at the end and 'plasticky. Vignetting. Footprint significantly.

Opinion: Used on 70d. rnrnMigliorato the feeling after a calibration of AF. Starting to look like what other users descrivono.rn The perception of quality 'constructive' and penalized by the fact that 'plastic, finished well, but still plastic'. Costa enough to expect more ', also another piece of plastic could mettercelo canon (the hood) they would cost a pittance, but the desire to make a profit on the sale to the exorbitant cost of the same is' turn up and naso.rnComunque 'bright and stabilized, this makes it usable in many circostanze.rn

Pros: All!

Cons: I do not think he has

Opinion: I have used and enjoyed, this lens for over a year. In my opinion he deserves the L without a shadow of a doubt. They make me smile "counter" that many have listed: RN1) will not fit ff (that 's why it's called EF-S!!) RN2) stretches during zooming (even the 24-105 and 24 -70 do and are and have been the delight of thousands of photographers nonostant what!) RN3) plasticky construction (are we really sure that ALL L are metal?) RN4) and not 'weather sealed (even many L "white "I am everywhere and yet we are working without problems) RN5) Price (tell me if you Canon or Nikon at home is something Aperture 2.8 and stabilized with a range of focal lengths similar at a better price) rnParlando serious things (and not discussing the sex of angels) in my opinion, and 'a great goal! focal range that allows you to do a lot of things. A very bright aperture, sharpness already at 2.8 that few have and a stabilizer that does its job well. What can you ask for more in a perspective??? RnIo recommend it to all owners of machines aps-c looking for a proproduct quality to use for sempre.rnLo I sold the 17-40 f4 L USM (very good lens) and gave me the most satisfaction of 17-55 ONLY when I needed a focal length of 17 FF. For ALL other applications (street, prtraits, reportage and travel) I regret to have that wonderful vebduto 17-55 IS USM!

Pros: sharpness, brightness, stabilizer, versatility

Cons: weight, price, building, distortion at the edges, flare

Opinion: I use it for about a year with great satisfaction, 95% perfect clean images and razor sharp images, excellent brightness and is also an all-rounder that lends itself to many uses from landscape to portrait, the street and another, and the 2.8 "is help shots in low light even freehand, good seal on the market of "usato.rnPer known as rigurda the mourners are the price in relation to construction (plasticky) is very high, the weight that is remarkable, that the flare is exaggerated I really suffer a lot, and in my case I find excessive distortion at the edges. rnrnNel whole I am satisfied of the "purchase, unfortunately if one day you decide to switch to FF you are forced to sell

Pros: Sharpness, brightness, stability, versatility.

Cons: Sucks a lot of dust, which may at this point does not affect the quality diell'immagine. Hood not included.

Opinion: I've used it with satisfaction for almost 4 years before moving to FF and on occasions not regret it. I think it's definitely the best all-rounder that you could want on APS-C. The building is not the best and it shows especially in the effect vacuum cleaner. In terms of image quality, perhaps the greatest limitation is the flare, which however is not excessive for a handyman. In summary: a lens next to the excellence that loses some point only for APS-C designed, and then built "on the cheap" compared to the L series that from the standpoint of purely optical in my opinion it deserves.
