Canon EOS 40D
Competitors

As well as being compared against other pro DSLRs, the Canon EOS 40D is also often compared to entry-level DSLRs. The Canon EOS 40D's top rivals come from Canon (such as the EOS 60D and the Rebel T2i) and Nikon (such as the D90 and the D5100)

Generally, some of the advantages of the Canon 40D compared to other pro DSLR competitors include: it has a slightly larger screen (3.0" vs 2.5"), lets you preview your photos on the screen, has a CMOS-family sensor (CMOS vs CCD) and has a built-in flash.

However, on average it doesn't record movies (none vs 1080p @ 30fps), has a significantly lower resolution screen (230k dots vs 920k dots), slightly smaller viewfinder (0.59x vs 0.71x), takes slightly lower resolution photos (10.1 MP vs 17.9 MP) and it's body is not weather sealed.
