Wahoo

Will send the housing back in a couple weeks.  Do I need reference number or just include a note?  What meter in the camera would I set to infinity?

I too just returned from a week using the D200 and Ikelite housing.  Had pretty much the same opinions as you.  I did loosen the shutter release lever and move its lever below/behind the rear command dial control so I could pull the trigger rather than push.  Had no problems.  Had one interesting problem.  With two DS200 strobes attached (Ikelite's dual cord) when the strobes fired full charge the flaching indicator in the viewfinder sticks and continues to flash stopping any further picture taking.  Easily fixed by turning strobe on and off, but took me awhile to figure it out.

Were these pictures from film or digital?  I've seen spots like this that I could only attribute to bubbles on the film during processing.
