The bayonet-style EF lens mount is at the centre of the EOS camera system. Breaking compatibility with the earlier [[Canon FD|FD mount]], it was designed with no mechanical linkages between moving parts in the lens and in the camera. The aperture and focus are controlled via electrical contacts, with motors in the lens itself.  This was similar in some ways to Canon's earlier attempt at AF with the [[Canon T80|T80]]. Other manufacturers including [[Contax]] (with its G series of interchangeable-lens 35&nbsp;mm rangefinder cameras), [[Nikon]]'s 1983 F3AF, and [[Olympus (company)|Olympus]] (with its [[Four Thirds System]]) have since embraced this type of direct drive system.  It is a large lens mount compared to most of its competition, enabling the use of larger aperture lenses.<ref name=canon>{{cite web|url=http://global.canon/en/c-museum/history/story07.html|title=Canon History Hall: Birth of New-Generation Autofocus SLR Camera, "EOS"|access-date=26 October 2016|archive-url=https://web.archive.org/web/20161026231954/http://global.canon/en/c-museum/history/story07.html|archive-date=26 October 2016|url-status=live}}</ref>
