All About Canon
Printed Information about Canon
As well as general advertising and promotional material for products, I come across printed material about Canon, the company. This is often literature released by Canon themselves.
Single Focal Length Lenses
EF Lens Accessories
EF Lens Technology
These booklets are really just advertising for Canon Lenses but they are very pretty to look at and there is some information in them.
They were published by Canon as a hard cover book some years ago and I see copies available on E-Bay and Amazon. Or you can read them here. Enjoy!
