Hi Steve, thanks for your words.
Before I buy the D50 I had a Nikon N80 on Hugyfot housing, it´s a great camera.
The D50 it´s very good camera too and also a very low cost. My idea is to use this camera on aperture priority as you told but as the strobes and sync cord from Sea & Sea do not support the iTTL the D50 do not understand that has a strobe connected and if I use the Aperture mode with a f11 , for example, the camera fix a slow shutter to compensate
The Sea & Sea has just made a converter to fix this problem, but I´m waiting to starts the sale on USA.
I´ll try to use the auto levels on wreck picture.
Thanks!
