[Canon EF-S 17-55mm f/2.8 IS USM] Perhaps the best lens made by Canon
From Reinhold Stansich
With the EF-S 17-55, Canon has a clear commitment to the APS-C format digital SLR photography delivered. Because, as the S in EF-S suggests this lens can only cameras on the APS-C series are used (this currently includes the EOS 20D, 30D, 300D and 350D) – for Vollformatkameras as the 5D, it is not suitable. The focal length range equivalent to a 28-88mm lens in 35mm conventional standards.
The pure performance of this lens are beyond doubt. The distortion at 17mm, although still significantly better than the competition. Only when vignetting at open aperture and 17mm focal length, the competitors a little better, but not significantly. The sharpness of the optics is sensational and is one of the best values ever measured. The chromatic aberrations are very well controlled. With 645g is relatively heavy and with 83×110mm, it is also relatively large – and is thus in the range of professional lenses from Canon. The autofocus is very fast and beautifully quiet and processing quality of the lens is very good and it fits comfortably in your hand. Relatively weak, it is at the minimum distance to the subject (which only allows 1:6 magnification). This provides a continuous light intensity of 2.8 and also an image stabilizer. Whether you take this light and focal length really needed was undecided – but it is indoors and in low light situations, but an advantage, because the tripod has not yet unpacked.
The only real downside is the price. The lens is located in a price range comparable with the pro lenses, their performance is also achieved. Only the lack of red ring and the non-guaranteed water tightness (but no matter, because the cameras for the lens is made is not waterproof) make the difference here. The sheer power of this lens makes an already swarming but the price also brings the ordinary to the ground of reality. I am ultimately responsible for the Sigma 17-70 decision, which is hardly where the data of this lens is reached, but by approx. 70% cheaper – than for the ambitious amateur need not necessarily be the best lens, it is also a very good made. To view the price savings is then added a super wide angle (for me the Sigma 10-20 EX) from.
