The EOS 5D Mark III is a 35 mm full-frame digital SLR camera for professionals and advanced amateurs. Basic performance is dramatically enhanced to meet diverse, sophisticated needs in terms of User Interface and photo outcome. The new model is a higher class of precision instrument down to subtle, hard-to-quantify details like hold, release sound, and matching of parts and coatings. Control layout is carefully designed calibrated for position, form, degree of protrusion, angle, and push resistance, letting users conduct operations by feel while looking into the viewfinder − also ergonomically designed for maximum user-friendliness.
