This is the perfect reference to keep with you at all times. If you're new to the T2i, it has everything a newbie needs to learn how to use every feature, and how to make each setting and custom function. Most important, it tells you why you should select a particular option. The booklet that comes with the camera tells you nothing more than what they do, not how they can affect your pictures. I really liked that this book was spiral bound, so you can open it up to any page and lay it flat, which is helpful if you refer to the settings tables that recommend particular settings for kinds of photography, such as indoor sports, outdoor sports, landscapes, portraits, concerts, general purpose, and more.
There are seven chapters in this little book:
Chapter 1: This is a setup guide. If you loan your camera to someone, they can read this chapter and know how to operate the basic camera controls in a few minutes.
Chapter 2: This is a useful roadmap, with separate pages showing each control and button on the camera, with a complete explanation of how to use it. No hopping around like in the Canon manual!
Chapter 3: All the Shooting and Playback menu options are carefully explained here.
Chapter 4: Setup and My Menu options are explained here.
Chapter 5: Very helpful chapter explaining how to use the built in flash and optional flash units.
Chapter 6: Finally somebody wrote a chapter on how to use Live View and shoot movies, with specific movie making tips and techniques.
Chapter 7: This is the chapter with tables that provide the author's recommended settings. I haven't seen anything like this in any other book. Why not?
This Compact Field Guide is a field guide in the true sense of the word and a must have accessory for every T2i owner's camera bag.
