I just bought a Canon Powershot s5 IS. I am just getting into photography and I was reading alot of reviews about this camera and felt it was a good one to start with. So far I love this camera. I have to get oriented with all of the different settings and features. I have never used a camera like this one before. What are some accessories I should look into getting? I have a 2gb SD card, rechargeable batteries and I know I am going to pick up a tripod in the near future.
