All digital cameras make good 4x6 prints.
You are looking for a film camera replacement that will suit a person that just wants to take pictures of the grand kids and a few tourist photos.
You have the right idea about getting a camera with no zoom.
Kodak has always made cameras that are easy to use.
So take a look at the Kodak CX 7300 (about $130).
For a little better lens quality, take a look at the Olympus D395 (about $150).
Both cameras use 2 AA batteries, and I would suggest you get NiMH AA batteries/with charger. Wal-Mart has one for $10 and comes with 4 NiMH AA batteries.
I am interested in buying a digital camera for my mother in law. All she will do is print from those online photo printers like shutterfly 4 x 6 photos. So what is the best digital camera that makes 4 x 6 prints as close to a film camera that is easy to use? It doesn't even have to have a zoom lens. Just nice quality 4 x 6 prints in a camera that is easy to use and that is not too bulky. Also would like it to take pictures in low light situations. Any suggestions?
