I have started researching camera housings for underwater video for my Canon 5D M2. Pricewise there seem to be two tiers.
First tier
Sea Cam (over my budget)
Aquatica(seems like good value/build quality)
Sea and Sea
Nauticam
Subal
Second Tier
Ikelite
Equinox
Aquatech
and Nimar
Are there any recommendations for any of these brands? I am looking to purchase the housing used.
