zoomlens for big stuff in stead of 10-17 fisheye ?

I have a Tokina 10-17mm fisheye, great lens if you can get very close, which is most of the time not the case for the big stuff (sharks,..). What are you forummembers using ? I was looking at the sigma 17-70mm but I can not find zoomgear for my sea&sea mdx housing (for my canon 7D) . Would maybe a teleconvertor 1,4 or 2,0 also be an option ?

Thanks for feedback

Hi Jan,

Yes, a x1.4 Tokina teleconverter would work but a better option would be the Canon 10-22mm which is my first choice if shooting sharks. I think you'll find the 17-70mm has too much reach unless you are looking for images with very close detail.

Thks Tim: is the 10-22 indeed that much of a difference compared tot the tokina 10-17 to be able to shoot sharks e.g. ?

The diagonal angle of view of the Tokina is 180 degrees at 10mm to 100 degrees at 17mm whereas the rectilinear 10-22mm is 107 degrees at 10mm to 63 degrees at 22mm.
