As I was discussing in this thread, I'm unhappy with the fixed-ISO of my current Canon camera, because it takes poor low-light shots, and I'm looking at options. Either a new camera or one of the suggested external flash units.

But at the moment, more importantly, my wife is looking to buy a digicam of her own whose primary purpose will be taking photos of real estate, both indoor and outdoor. She specifically wants to get natural-light indoor shots of the homes (i.e., not a flash picture, but a nice natural light picture). That means it's going to have similar low-light requirements as what I'm looking for.

The following are going to be the requirements for her camera:

- Very good at low-light and natural-light shots indoors. Imagine, say, a dining room with light coming in from the windows.

- Relatively compact and rugged. Imagine it going into a woman's purse.

- Relatively inexpensive.

- Simple enough for a non-tech to use.

Everything else is pretty much nonissues, such as pixel resolution, battery life, memory card type/capacity, yada yada. The above requirements are going to be tough enough to intersect, I suspect.

I'm trying to browse at www.dpreview.com , but their features search does not include an ISO rating as one of the search options. Anyone have any suggestions?
