My wife wants a new camera for X-MAS. I don't know the first thing about them. She currently has a point and shoot digital camera that is about 7 years old. She is looking for something a little more advanced than point and shoot (something she can manually focus and also has auto focus). What is a good brand (Nikon, Canon...something else)? I am looking to spend about $600-$700 (no idea if that is too much or not enough). One more thing...it has to be relatively simple to use. Any suggestions? Thanks in advance for any advice.
