Tokina 10-17mm

Hi

Forgive me for repeating a post on another channel but I didn't get any response to my question.

I have a Nikon D700 with nauticam housing and a sigma 14mm wide angle.

I've heard much talk about the Tokina 10-17mm and am wondering how this would differ from the sigma that i already own. Now that Tokina came out with the new model, what are the advantages of having that lens in addition to the sigma? Or am i just duplicating? The D700 is an 'fx' model.

Thanks

Allan

Your 14mm is a rectilinear lens. The 15mm Sigma fisheye is significantly wider and is excellent underwater. The Tokina10-17 has some use on FX but is limited. The 10-17 is a fisheye zoom optimized for DX, to get the same range on FX you must use it with a teleconvertor. I have done this and posted results here on WP if you do a search. If you do not use a TC it will crop the image below about 13-14mm. The combination with TC loses one stop of light which does effect focusing etc in low light. The combination with TC works well in bright light like snorkeling at the surface with large animals, quality is decent but not exceptional.
