In the end, artificial lighting is needed at any depth much below 5m.
#316177 A VERY good reason to buy equipment insurance!

Bad news, all around. But no insurance? That's silly...
#314460 Black Water diving - lighting advice

I suspect that a 105mm will be difficult to use as the field of view is small. A 60mm might be easier.
Lighting is tricky as jellies like side-light but cuttles etc a more traditional angled light. Moving your strobe arms around at night can be tricky, too. I would shoot at a small aperture with half power or less, but try sTTL, too. A good focus light is essential, as well as a torch (I mount one on my right BCD strap) angled diagonally across the chest to illuminate strobe and camera controls.
I would guess that snoots are irrelevant against a black background, and just make it even more difficult to aim your strobes.

#314062 buying used underwater equimpment

If you are near to an underwater photographic society, get in touch: I've sold an old camera and housing that way, to a new member who was interested (I think he later went out to Antarctica!). On-line, I've found that eBay and Amazon are quite frustrating experiences..
... Wetpixel (and Digigreen in the UK) are pretty good, as most people are genuine enthusiasts and happy to see their old pride and joy go to a new home.

Cold water images from a couple of weeks ago in Plymouth, Devon.
Thanks to Maid Maggie II for delivering the divers to the diving, and Gordon Brown (who knows that he really wants a shiny new D800) for crab-spotting.
Nikon D800, Nauticam NA-D800 housing, Sigma 15mm + Kenko x1.5 T/C, Anthis/Nexus 12-24mm custom dome (Nauticam adaptor), Sola 600 LED light, ISO 1600.

#313731 From DX to NEX?

I've been through this is some detail in the last couple of months, and opted to stick with DSLR because of AF issues, lens choice, low light performance and the ability to print large images...

#313001 Offensive imagery

Sad to say, Dr Allen and his colleagues were seen in a similar situation in a BBC documentary not so long ago. Because even slight contact with coral is thought to cause damage, we have to regard these practices as unacceptable today. It is a throwback to the mind-set of an earlier science, whereby the end justifies the means in ecological research.
At last weekend's British Society of Underwater Photographers competition an image was barred because a starfish had been lifted from the reef. "Look, don't touch" is now a guiding principle, manipulation of subjects and of their behaviour is increasingly frowned upon in all wildlife photography...
... although I would also like to congratulate Maurine and Mark on the book, and have great respect for Gerald Allen's work over the years.
