For those of you who have the above Sony cameras, I would highly recommend getting this ebook. Gary's ebooks are amazing. He goes into great detail on how to use the camera, what the settings do, etc.. Each time I have bought a new Sony camera I have got the ebook for it as well. The book is only $31.45. IMHO it is well worth the money.
