Eyepoint / Viewfinder / LCD - Scene framing
I'm about to buy the D70, and of course will consider a housing for it someday. I currently use a Coolpix 950 in an Ikelite housing, and am concerned about using a viewfinder.
With the non-SLR digicams, the LCD provides a 'live' view from the camera's lens, making it IMHO quite a bit easy to frame a shot. I can poke the camera into a crevice and still be able to see whether the octopus is still in the scene, while hanging out upside down and swimming against the current (standard practice in the Puget Sound).
Putting my mask up against the back of a housing, looking into a tiny passive optical viewfinder through several air spaces, three glass plates, some water, as well as a mirror / prism seems to me like a real disadvantage.
I've been a huge fan of the Coolpix swivel lens, and really wanted to develop an U/W housing that made use of that feature, so I could look down, or angled into the camera, rather than having to place my face directly at the back of the camera. Aquatica had a great idea with the Coolpix 995 housing, with the 45 degree LCD angle. I honestly don't know how U/W photographers frame their pictures when the camera is sitting on the bottom.
Any comments on the use of DSLR viewfinders???
