tingkka:it seems like a lot of people get nexus and aquatica. i guess they're the best two housings out. i was looking into Sea&Sea and Light&Motion.
We should have a physical vote for Nikon Nook. i'll put up a vote on a new thread. you guys should all vote~
Warning, strong opinions about to happen!
Disclaimer, I'm an Aquatica dealer and theoretically an Ikelite dealer.
Nexus and Aquatica are not the best.
Subal and Seacam are the best, but they are not without their quirks. Wierd handles and top of housing strobe mounts are not the greatest. They both offer great construction, optional viewfinders that are fantastic (to die for) and some awesome ports. Bad news, they cost more than anyone else's. The optional viewfinder for a Seacam costs more than an Ikelite housing. Are they worth the extra cost? I don't know.
Nexus is a little cheaper than the Subal. This is a very nice design. The size of the housing is minimal. The port system is very secure. Nexus housings tend to look like crap after a few years, but are in fact very rugged. I can't imagine anyone being disappointed with this housing. In the "less than a car" price range this is the nicest design.
Aquatica's housing is based on the tried and true A90 housing, as is the Digital Rebel housing. This is the "best bang for the buck" housing. You get an aluminum housing based upon a solid design. Excellent and reasonably priced port system.
Sea and Sea used to make superb (and expensive) aluminum housings for film cameras. They went to a composite "one size fits many" design for digital SLRs. It's just the same. For the same price you can get an Aquatica. If you want a plastic box, get an Ikelite and save some real money.
Ikelite makes a good housing. I was never thrilled with their port system. If you need to save money, it's an excellent choice, but not the best choice.
After a week on a boat with different photographers and different housings and different cameras, I was re-inforced with the idea that it didn't make that much difference.
