Canon 18.0 MP
Canon's X0D series was, for many years, essentially the default choice for keen enthusiasts, professionals and aspiring-professionals who wanted top-level image quality and functionality without the bulk (or price) of a pro-level camera such as the 1D series. The 10D, 20D and 30D were hugely successful and popular cameras, and you didn't have to spend long shooting with them to understand why. However, like every other sector of the DSLR market, there are some very competitive rivals, in terms of both price and features. Cameras such as Sony's A700 and Nikon's D200 and 300 have meant the most recent X0D EOSs have been held to higher standards and have found it a little harder to stand-out.
