After getting a taste for going digital with my Fisher Price, sorry , Kodak DX3700 I'm going to upgrade to something a little more portable and speedier. I'm going to keep my 35mm SLR for a while, but wanted something small and versatile as a take-anywhere snapshot camera. Have been considering the Pentax Optio 330 (or maybe 430) or even the Canon Ixus v3. (By the way what is the difference between then GS and RS flavours of the Optios?) Both seem very nice compact cameras. Am a pretty enhusiastic amateur photographer (more enthusiasm than actual skill ), so want something that is small, has optical zoom, and is fast - i.e. quick boot up, fast between pictures etc etc. So a few quick questions: 1. Does the difference in resolution between the 330 and 430 make THAT much difference? 2. What's the quality of the images like on each? 3. The movie-mode on these cameras sounds good (with the Canon having the advantage of recording sound too). What's it like? 4. Are there any other features on either of these cameras which sets it apart? 5. Any others I should be considering? Lots of questions I know, but ANY suggestions or comments are most welcome!
