in june i'm leaving for australia for a month. i'm going to be doing mostly snorkling (around 5-6 hours a day) and a little diving (once a week). I'm looking to get into photography besides the simple point and shoot (i've used a canon s200 underwater while diving). I currently own an olympus c-60 which is a nice camera and has some options (apeture and f-stop). I know i can get a underwater case (olympus pt-024) for this camera, but was wondering if it'd be wise to sell the camera and get something with more options. I don't want to spend a lot of money. I was thinking of an olympus c5050 or c5060 and its accompanying case. I know i'll be going down 1 megapixel. Any advice to whether or not this is a good idea, or should i stick with the c-60. Maybe another camera i wasn't thinking of. I'd like to be able to use lenses (i really like macro photography).
Thanks for your help,
Mike
