Canon’s “Lens Work”

Canon has published its “Lens Work” book over the years, detailing design, specification and usage of its entire lens line. It’s well worth reading at least once, and is a good reference. Now Canon has posted updated electronic material (11 PDF files) available in multiple languages, though certain lenses like the EF 14/2.8L II are not covered.

PDFs 3, 4, 5 cover Canon EF primes, zooms and EF-S lenses respectively. This is an excellent way to investigate your next lens choice.

Perhaps most useful to to the widest audience (and not just Canon shooters), is book #7 The Basics of Interchangeable Lenses & Correspondence of EF Lenses to Digital Photography, which offers an excellent explanation (and graphics) of how lenses work on a camera, angle of view, sensor size cropping, depth of field, perspective and digital imaging. Even those with previous experience will find this book interesting. PDF 8 Photo Techniques discusses various types of picture taking (portraits, landscape, etc), and is an excellent introduction for beginning photographers.

PDF 9 EF Lens Technology covers Canon lens design, and PDF 10 Optical Terminology are well worth reading if you want to understand lens performance—design challenges, compromises, MTF, lens aberrations, etc. It also has MTF charts for all Canon lenses. Finally, PDF 11 contains design specifications and tables for Canon lenses and accessories.
