The Rollie is a good camera, and you don't want an internal flash. If you need a flash, get something you can take off of the camera and bounce off of the ceiling or a wall or something like a reflector. The internal flash on any camera that has one is ONLY meant to be used for fill lighting on clear days when the light from the sun is harsh and is giving you really dark shadows. If you try to use it for a main light source, the results will be horrible. Everyone will look like those stand-up cardboard cut-out figures. One problem: that f/2.3 lens is not very bright and if you are using it indoors, you will probably get some photos with motion blur. It's really an outdoor/daylight camera.
That said, for most people photography (especially groups) you would probably do better with a rangefinder. If you want something easy to use, the Yashica Electro 35 GSN, the Canon GIII QL-17, and the Minolta Hi-Matic 7s are all good, have autoexposure options and have much better lenses for photography in lower light (f/1.7 and f/1.8 ). You'll be slightly more involved in the photo-making process (you will have to focus, but that's easy with a rangefinder).
does someone know a solid and cheap point and shoot camera (for parties)?
At the moment I'm looking for a Rollei XF35 (~$20 - ebay) - it has a nice lens (1:2.3) but maybe an internal flash would be better, especially for dimmed light?
Thanks in advance!
