Being relatively new here, please accept my thanks to all for a wonderfully informative and friendly site : I've learned a great deal, but obviously have a long way to go.
I recently purchased a Nikon D300, Sea and Sea housing with a Tokina 12-24 and dual Sea and Sea 110a strobes. Photographing has been a great experience.
However, a friend was using a sigma zoom lens on a D90 with Ikelite housing, and I realized that it would be very useful to bring the larger, and sometimes rather shy bigger fish in closer.
Can I ask what you guys recommend?
Many thanks!
