Rear retainer trim for Caonon EOS

Rear retainer trim for Caonon EOS

It is necessary with some (full frame mostly) EOS cameras to trim the
rear element retainer to prevent contact with the moving mirror.
Here the ring is chucked into a lathe and about .75mm is turned off.
The ring is then painted black.
