The Compact Field Guide for the Canon® EOS® 7D is better than the user manual but not by much. It is written in clearer language and many settings are better explained than in the manual, but it is not very thorough, does not include examples, nor go into details about why you may choose one setting over another. The author has also written a much larger book entitled “David Busch’s Canon EOS 7D: Guide to Digital SLR Photography” which is said to cover the 7D in much greater detail.
From the author:
Just the essentials for your Canon EOS 7D
When a command card doesn’t provide enough information, and a small camera guide has too much padding, pull this Compact Field Guide for your Canon 7D out of your camera bag and get the advice and recommendations you need quickly.
I don’t believe you can have too much of a good thing, but readers who have been using my 500-page in-depth guide to master their Canon 7D have asked me to distill the most essential information into a portable field guide for on-the-go reference. In the approximately 150 pages of this lay-flat, spiral-bound book, you’ll find in-depth descriptions of every control, menu option, and capability of the Canon 7D. Each choice is accompanied by my recommendations and a description of when you should or should not use a particular setting.
I rate this book an 8 out of 10 and useful for Canon 7D users who need a replacement for the user’s manual.
