Canon EOS Camera Linup

The Canon EOS System is composed of Canon EOS camera bodies, lenses, Speedlite external flashes and several lens and camera accessories. This article will discuss the current line-up of Canon EOS camera bodies.
Canon has varied line-up of nine digital SLR camera models. The current production line-up includes four entry-level, three mid-level and two professional level bodies, though some would argue, the Canon EOS 5D should in fact be considered a pro level body. Only the lack of a weather-sealed body keeps it out of the professional ranks, although none would argue that its image quality is certainly up to "pro" standards. Of course, these level designation refer to the camera's features. There are numerous professional shooters using Rebel XTs and 40Ds. On the other hand, even 1Ds Mark III in inexperienced hands can produce rather poor images.
