I'm currently looking to get a new point and shoot camera. I currently have a Sony cybershot 7.2 megapixel that I just really dislike. It is to bulky for me and I can never seem to get it to do what I want. Plus I hate the dial with all of the different shooting modes because I've had a lot of problems with it randomly changing scenes. The 3 cameras I'm thinking are the following. Most of the photos I take are just of friends at bars and such, but I do enjoy doing some other photography from time to time. Canon PowerShot SD750 - This was my old camera that broke and was replaced by the Sony. I loved this thing and wouldn't mind going back to it. 250$ Canon PowerShot SD870 - This looks is a 100$ upgrade to the 750 with more zoom (3.8 vs 3.) and 1 more megapixel. (8.0 vs. 7.0) I don't really care much about the extra megapixel but the added zoom is nice, but I'm not sure if its worth 100$ extra. 350$ Panasonic Luminx DMC-TZ3K- This camera just sounds amazing. 7.2 megapixel, with 10x OPTICAL zoom. On a point and shoot thats just unbeatable, however I've never used a panasonic camera and I really don't want to deal with the same frustrations I've dealt with while using my Sony camera. 250-300$ Any opinions would be appreciated, thanks.
