I recently bought the Canon S3 IS digital camera (which is awesome by the way) and needed a new camera bag. Well, after a long and exhausting search, I finally decided on the Lowepro Rezo 110 AW Camera Bag . This bag works perfectly. I am able to fit two extra sets of batteries, four SD cards, my polarizer lens, and my Canon S3 with the canon leather strap and the lensmate adapter. See pics below.
This came in handy for the IPFW Fall University Singers concert yesterday (pics of that to come soon).
