For G3 users

This could be described as the Missing Manual for the Lumix G3. An e-book written by Reed George, it covers all the functions available through the menu system and how Reed, uses them -- or not, as the case may be. From his explanations you can get a clearer insight into their utility.
In the end your photographic requirements might mean you choose differently from Reed, but I'll bet for some of them it'll be the first time you'll know why & how you're making your choice! I know it was for me.

Highly recommended.
