It probably also applies to other DSLRs, as well, but since I don't test them I won't speak to applicability of this information for them.
Canon EOS 1Ds Mk III review | Like other professional DSLRs, notably previous EOS 1Ds models and Nikon's D2x/D3, the EOS 1Ds Mk III is much taller than the average digital SLR. A big, fat battery housing sits in the base of the body, and this also allows space for an additional, vertical shutter release. Reviews | TechRadar
