This unique manual is better than the manual that comes with your camera in several important ways:
It's organized according to efficient workflow, so you can get the most out of your Sony A100 quickly and with the least amount of bother. You can find what you're looking for interactively: by using the interactive Table of Contents, choosing one of the questions in the Quick Answers section, or by following any of the convenient links we've placed throughout the document.
It's not a book (unless you want it to be). It's a PDF that you can read on your computer or on a PDA that fits into your camera bag. It is laid out on an 8.5 x 11-inch "page" so if you want to print, you won't have to waste paper or spend time configuring your printer.
Because it's a PDF, you can find subjects you're looking for by searching electronically. Typing Cmd/Ctrl-F brings up the familiar search dialog. So all you have to do to jump straight to all the references to a particular part or feature is to enter its name. (No reliance on a mindreading indexer.)
The PDF is photographically illustrated so you can see exactly which combination of buttons, knobs, wheels, and menu choices will help you make the magic you are hoping for.
In addition to teaching technically correct procedures, this document offers valuable hints for taking photographs in some of the toughest situations.
