Yesterday i was loaned a book by a family friend,
“EF Lens Work III, The Eyes of EOS”
it’s a publication by Canon, which details the entire EF lens range as well as a world of information including -Choices of lenses for different types of photography
-Full Technical specifications on the EF and EF-S lenses
-Theory of light including, reflection, refraction, optics and lens theory
-Construction and technical operation of the IS (Image Stabalisation) and AF (AutoFocus) systems.
There is also a downloadable version (in parts) available for those unaware of books!!
It can be found HERE
From what i’ve read so far, it’s a brilliant learning resource combined with an array of Canons marketing material. It is even very beneficial for the non-Canon users out there who would like a little more depth into the how and why’s of lens operation and science.
