So I have a working e-pm1 that was dropped and got a crack on the housing. Since I don't care if it breaks or not anymore, I thought why not get one of those ziploc bags and use it for snorkeling for my upcoming trip to Hawaii? So I got this: Amazon.com: DiCAPac WP610 Large Camera Waterproof Case for Canon, G5, 7, 9: Camera & Photo Tested in a sink, no leaks. Now I need a cheap lens to go with it, and in my bag I have a Sigma 30 and Panny 14. Leaning toward 14, but I wonder if I should go with the longer reach... that and the 30mm is sub $100. my thinking: Panny 14mm - wide angle seems more logical for snorkeling, as I'll be in shallow water. - f/2.5 vs 2.8 might help a little since I won't use a flash. - wide angle means camera shake has less effect? - less overlap with the PL25 I'm bringing to use on land. Sigma 30mm: - cheaper so I won't be as sad if things go wrong. - longer reach so I don't have to get close. I also have a Oly 45mm that can fit in the case, but I am not sure if I want to put that much money in a ziploc. Also, any tips for snorkeling photography anyone can share? Thanks.
