• the Canon EF-S lenses are designed for the Canon EOS APS-C cropped sensor dSLRs with 1.6x crop factor and thus have a smaller image circle which prevents these lenses being usable on Canon 1D or full frame dSLRs
• the early versions of the standard zooms were particularly poor that they were an embarassment, thankfully version II were significantly better but still not great
• unlike the Olympus Four Thirds dSLR system lenses, none of these are pro quality, none are weatherproofed, none have an aperture wider than f/2.8, and would struggle to beat even the consumer range of Olympus Four Thirds dSLR system or Micro Four Thirds system lenses in terms of optical quality across the frame.
• do yourself a favor, look at the better Canon EF lenses if you must have a Canon cropped sensor dSLR, or reconsider whether you really need a dSLR and could do with a more usable, compact and better optical image quality system - Micro Four Thirds system
• Canon do not make a fisheye lens for their cropped sensor dSLRs, unlike Nikon, Olympus and Panasonic, so if you want fisheye in a Canon, you have to get a third party lens or buy a full frame dSLR.
