I have been poring over posts in anticipation of a 2nd trip to Palau in a few weeks. I have been stressing and need some advise.
My camera setup is: Nikon D300, Sea&Sea housing (I have most all the ports, extension rings, etc.) Inon strobes.
Lenses that I use underwater: WIDE ANGLE: Tokina 10-17 (LOVE THIS LENSE!), Nikkor 12-24. I have a #2 dioptor, and used it a few times until I got the 10-17. MACRO: Nikon 105mm (no VR, older lense).
I also have the setup for a Nikon 18-70mm lense. The ONLY recent time I've used this lense is in Palau. But, I am not happy with the quality, the distortion around the edges. Had to crop many of the pictures extensively.
Obsessive side of me: In an attempt to not miss a shot -- I was thinking about taking the 18-70mm, or obtaining a simlar (but better) lense that is more of a mid-range zoom. In Palau, being tied off to the reef on sites such as Blue Corner, you do not get close to the sharks. Alex Mustard mentions the Nikon 17-35mm quite a bit. I've also seen posts on a Sigma 18-50mm lense.
Practical side of me: I have almost convinced myself that I should not even attempt medium zoom pictures, because of the distance to subject, clutter in water, quality,etc. Most of the "zoom" shots, I end up trashing anyway. Should I just let the other photographers, videographers get the blue corner shots? Focus on shots of things I CAN get close to and bypass those I cannot?
Thanks!!
