As well as being compared against other pro DSLRs, the Canon EOS-1D Mark IV is also often compared to entry-level DSLRs. The Canon EOS-1D Mark IV's top rivals come from Canon (such as the EOS 5D Mark III and the EOS 1D X) and Nikon (such as the D4s and the D3S)

Competitor classes

compared toPro DSLR competitors

Generally, some of the advantages of the Canon EOS-1D Mark IV compared to other pro DSLR competitors include: it shoots faster continuously (10 fps vs 6 fps), has slightly less shutter lag (104 ms vs 206 ms), has a slightly longer battery life (1500 shots vs 980 shots), uses fast phase detection autofocus (phase detection vs contrast detection) and has slightly more focus points (45 vs 19).

However, on average it is slightly more noisy at high ISO (1,320 ISO vs 2,293 ISO), significantly smaller viewfinder (0.59x vs 0.76x), takes slightly lower resolution photos (16 MP vs 20.9 MP), has a slightly smaller sensor (APS-H 27.9x18.6mm vs full frame 35.8x23.9mm) and lacks a built in HDR feature.
