I now use a Nikon
F90X camera in a Subal F90
underwater housing, and use a
Nikon SB25 speedlight in a custom housing made by Kevin
Cullimore (0181 529 6493). I use a
Nikkor 20mm for
wide angle work, and a
Nikkor 105mm Macro
for close work, although I also have a
Nikkor 24-50mm
zoom which I use on occasions, and a
Nikkor
Fisheye 16mm (180
degree full frame fisheye!) which I use infrequently, mostly on clear-water wrecks.
I now have a second identical camera and housing which is mated to a
YS120 strobe mounted on an
Ultralight arm, and occasionally use a
YS30 set as a TTL slave.
You'll find technical details about Subal housings on the
Ocean Optics site, (as they are the UK
distributors), or at Subal Austria. Details of Nikon cameras, lenses and accessories can be found at
Nikon Imaging or at
B&H Photo-Video, not forgetting of
course the UK's premier Nikon shop, Gray's of Westminster
