Canon EOS 5D

Manufacturer: Canon Type: Camera (DSLR, full-frame) Year introduced: 2005 Resolution: 12.8 megapixels

Overview

The Canon EOS 5D was the first affordable full-frame DSLR, announced in August 2005 (^[1]). While Canon’s EOS 1Ds and 1Ds Mark II had previously offered full-frame sensors, their professional price points limited adoption. The 5D brought 12.8-megapixel full-frame imaging to a much broader market, and its announcement triggered an immediate “housing race” among underwater housing manufacturers.

The full-frame sensor was particularly significant for underwater photography because it restored the full field of view of wide-angle and fisheye lenses that had been cropped by APS-C sensors — a persistent frustration for UW photographers who relied on ultra-wide coverage. This made the 5D enormously appealing to the community.

Ikelite won the housing race, delivering the first production Canon 5D housing in time for a review by William Heaton in December 2005 (^[2]). Nexus was also planning a 5D housing alongside their 1Ds Mark II housing (^[3]).

The 5D’s impact extended beyond its immediate generation — it established the precedent that full-frame sensors would eventually become the standard for serious underwater photography, shifting the industry away from the crop-sensor compromises that had defined the early digital era.
