Before I start this review it's worth mentioning that I'm sure many professional photographers will disagree with what I'm about to write, however I've tried to give a fair review of this lens based on my own experience of using it.
This is the "Canon EF 24mm f/2.8 IS USM Lens" a prime lens with features including a fixed focal length of 24mm (meaning there is no zoom), however on APS-C cameras with the crop factor this is equivalent to 38mm. A maximum and constant aperture of F/2.8, image stabilizing, an Ultrasonic motor and a distance scale for focus.
Image quality is pretty good regardless of shooting conditions. As you would expect both low light and action photography is where this lens excels. This allows you to both shoot hand held with a wider range of shutter speeds without having to mess around with the ISO and reduces the times where you need to use a flash in low light. Images are generally very sharp however some signs of softness were clean under some settings and conditions - the kind of which I'm only use to finding in cheaper lenses.
The build quality of the lens isn't really what I would have expected both from Canon and at this price lens. It's not unreasonable but I would have expected more. The front threads which you use to attach filters are poor, meaning I actually de-threaded a UV filter something that I've never done before. The lens hood while good in itself also is far, far to easy to over tighten to the front of the lens.
None of the photos I captures showed any sign of distortion and or aberrations, but glare was a problem on more than one occasion. However worth a note is the USM which was fast to focus and very quiet when in use.
The main problem I had with this lens is that I was using it with a Canon 600D (with the crop factor) is that the focal length doesn't really work for me.
At 38mm effective it's to short for the likes of portraits, pets, street and wildlife but at the same time far too wide for landscapes or indoor photography. Here in lies the problem as there are plenty of cheaper lenses (including some prime) that offer a far more useful focal length with a similar image quality and aperture.
Would this lens suit you? To be honest I don't really know. While it has a few good features I found it very average again considering the price. For me the focal length was the nail in the coffin, as every time I used this lens I ended up switching it for a shorter telephoto or a longer telephoto. If you need a fast 24/38mm lens then it's worth considering but only if you really need that length. There are cheaper 24mm lenses on the market as well as the very popular Canon 50mm F/1.8
