This is a very good lens. The UD (ultra dense glass) element helps to correct colours and it is quite sharp. The aperture at f/2.8 is wonderful. It is pretty sharp wide open, and typically great around f/8-11 (though most lenses are) It has IS which is not all that necessary at this kind of range as...

It is a great general purpose lens for every day photography ,fast focus ,great picture details with low light capability . With lens hood it it has a wow factor ! But some how EF 50mm f/1.4 usm is more practical and easy to use if wide angle is not your need of the hour !

The premium standard zoom for APS -C sensor cameras usually covers the range from around 17mm to around 50mm and has a maximum aperture of f/2.8. In 35mm terms this coverage is equivalent to something like that which a 27-80/2.8 zoom would have on a full frame camera.

Canon makes two distinct lens ranges. The EF lenses will fit any of the EOS bodies, but the EF-S lenses will only fit Canons with the smaller APS-C sized sensor. That includes the EOS 1000D, 400D, 450D, 40D and new 50D.

I've had this lens for 5 months now and I find it to be outstanding. My photo's are extremely sharp, vibrant and colorful. The focusing is fast, though not as quiet as an STM and works beautifully. I use this lens with the 70D and recently went on a trip to Jamaica ..

I have used this lens for about five months now and shot several hundred pictures with it. It's used only on a 30D body. Some people have noticed barrel distortion and some pincushion issues with their lenses.

Build quality; Fast maximum aperture; which takes advantage of the finer 30D autofocus capabilities associated with f2.8 and faster lenses; Superior picture quality

Wish the short focal length was 15mm; Not dust sealed like the L lenses; Fits only digital Rebel; Rebel XT; Rebel XTi; 20D; 30D; and probably the upcoming 40D (or whatever they call it); Attracts a lot of attention; especially with the hood attached; Lens hood doesn't come with lens; is expensive (I...

Very useful lens

A quality modern mid range zoom for 1.6x crop with all the bells and whistles, constant F2.8, IS & USM. A bit soft at wide end at 2.8 which becomes sharper at f4. Like to see this lens upgraded to L quality for around the same price. Shoots good images but so does the 17-85 at f4.

Good images; IS; mid range zoom

Little Soft wide @2.8

I've used this on a 50D and 7D mkII; it produces first class results on both.I'm sure if it were an EF lens and not an EF-S lens, it would have a red ring and be an L lens - the quality is that good
