Yes, it is a Canon EF-S lens.
The 24, assuming you have an APS camera, would be the 35mm equivalent of about 38mm, not what I would consider wide angle. Even the 17mm is only marginally wide angle on an APS camera IMO. I also have the Canon 10-22mm zoom when real wide angle is needed.
I'm using it on a full frame sensor camera, and it's pretty wide :) Does great outdoor scenery with a wide 2.8 aperture ... Should I consider getting something with wider dispersion? I thought I had it covered between my 24-70 Zeiss and my 70-400 Sony G.
