Does the lens mount material – plastic or metal – make a difference?
Low-end Canon EOS film cameras built since the early 90s have used lens mounts made of polycarbonate plastic. (the EOS Rebel Ti/300V/Kiss 5 being the sole exception) All other EOS cameras, including all affordable EOS digital cameras to date, use lens mounts made of metal. The main advantages of the plastic mounts are that they re very lightweight and cheap to manufacture. Polycarbonate plastic is pretty tough, and although you could probably break such a lens mount if you really tried, most people don t have a problem. Besides, if your camera took a blow strong enough to crack the lens mount you d probably have other problems with it too. The main advantages of metal mounts are that they have superior resistance to abrasion and they look posher. So if you hardly ever change lenses then plastic is probably just fine. But if you frequently change lenses you ll probably want a metal mount, since it won t wear down as quickly. A heavily worn lens mount could, in theory, fit much more loos
