Canon EOS-1Ds Mark II
Competitors

As well as being compared against other pro DSLRs, the Canon EOS-1Ds Mark II is also often compared to entry-level DSLRs. The Canon EOS-1Ds Mark II's top rivals come from Canon (such as the EOS 7D and the Rebel T3i) and Nikon (such as the D700 and the D3)

Generally, some of the advantages of the Canon EOS-1Ds Mark II compared to other pro DSLR competitors include: it slightly larger viewfinder (0.70x vs 0.62x), has a slightly larger sensor (full frame 36.0x24.0mm vs APS-H 28.7x18.7mm), slightly better viewfinder coverage (100% vs 98%) and has more storage slots (2 vs 1).

However, on average it doesn't record movies (none vs 1080p @ 30fps), has slightly narrower dynamic range (11.3 EV vs 11.9 EV), has a much smaller screen (2.0" vs 3.0"), has a significantly lower resolution screen (230k dots vs 920k dots) and doesn't let you preview your photos on the screen.
