>*Are* our metal lens mounts steel? Or aluminum?
Stainless steel.
Incidentally, metal mounts are not immune to wear. It is not unusual for
Canon Service Centres to replace the lens or body mounts of equipment
which has received heavy professional use. After all, what other
precision mechanical equipment rotates two metal surfaces in opposite
directions without lubrication?
Plastic lens mounts are actually made of polycarbonate resin with glass
fibres added for strength and rigidity. This material is less abrasive
and more elastic than metal.
Metal mounts may offer a better look and feel than plastic, but there is
no evidence that they are more durable than plastic mounts for the lenses
on which they are used.
