Will it looks like I'll be trading my Nikon P50(which replaced a lost A570) with my brother for an A570. Ikelite opted to not making a housing for my P50. Since I will not need to buy yet another camera, and the Canon housing is cheap online I think I'll get a strobe set up. Whats a good choice that won't break the bank. Also what are my options for wide angle setups. Should I just leave the lens on or is there certain times it would be beneficial not too. Since I lost my first A570 on my first dive in Bonaire last year, I havent had much time to practice.
