Greetings -
I'll start by telling you all that I'm not the photographer in the family, but have
been outfitting She Who Is with a new camera (D200), housing (Titan) and a
pile of lenses:
Tokina 10-17
Sigma 17-35
Nikkor 60mm
Nikkor 105VR
plus for topside
Nikkor 18-200VR
Tokina 80-400
She also has a few other lenses from her older Nikon cameras (a 2020,
which we still have, and a D70, which we recently sold). This is also her
first housed digital SLR - she has been shooting various Olympus cameras
(3030, 5050, 7070) under water for years.
In any case, my quandary is the Sigma 17-35. Light & Motion doesn't support that
lens, but I'm wondering if it could be made to work anyway. I've asked them
directly and the answer I got was "we don't know". <_<
While it's not critical, it would be nice to be able to use it. Light & Motion does
support the Nikkor 17-35 lens.
The Nikkor is 82.5mm in diameter, and the Sigma is 83.5mm, so there's a small
chance that the Titan's gear for the Nikkor would work.
However, the Nikkor is 106mm in length, while the Sigma is 88.7mm, so I'm guessing
that a different extension ring would be required. There appears to be 4 different
extension rings that Light & Motion offers, creatively named Extension Ring [1234].
The Nikkor lens requires Extension Ring 3.
Any advice appreciated - which could include "use the 17-35 topside and just shoot
the 10-17 under water".
