I'm not sure how to really ask this question, and I am sure there are as many answers as there are way to pose this, so...here goes a shot.
Which housing , for my D80 that I am getting for Christmas
, might be appropriate for me? I'm not a beginner. My point and shoot is frustrating me beyond all belief. I just can't adjust things to get the shot I want. That is why I am making the jump to DSLR. I'll probably never be a professional, thus my wanting a mid level DSLR, not a D2x or something. I want something I can grow into not out of and do more with than print 8.5 x11's for my wall.
A brand such as Ikelite is near the bottom of the price range. Very good, yet heavy above water by 2-3 lbs. over aluminum ones. I believe they work best with their proprietary strobes?
Another brand, such as Sea & Sea, is a few hundred dollars more. Is it worth it? I don't see too many with this brand. Does it do the same job as Ike or a more expensive brand like:
Aquatica. This one is several hundred, if not a thousand dollars, more than Ike. By spending some time here, I have found that more of the Professionals use this caliber of housing. Is it lighter to carry? Does it have better buoyancy characteristics? More access to camera functions?
What makes a particular housing more desirable? I persoanlly like the aluminum ones because they are more form fitting and "sexier" than a square plexiglass case. Is this enough of a reason to spend the extra money? I know someone is going to say, "go pick one up or try it out". Unfortunately, with my current schedule, I'd be skipping the one weekend per month I get off work and the day of diving to do that. Please help me to understand the differences. Thanks!!
