I have a D300 and a Seatool housing, along with the Nikon 105mm fisheye and Nikon 105mm VR lenses and corresponding Seatool ports. I also have the Tokina 12-24mm lens but no port (don't think Seatool support it), and i'm planning to get the Tokina 10-17mm.
After using the above set-up in the Red Sea recently (day diving out of Sharm), I found that for many dives there was very little macro or wide-angle opportunities, and the fisheye and macro lenses were too "extreme" for shots of morays, scorpionfish etc.
So, what would be a good next lens for those dives which aren't going to be specifically wide-angle or macro?
thanks,
Jon
