Which S&S port for Tokina 12-24?
Posted 28 March 2008 - 10:31 AM
S&S recommends the fisheye dome port.
if not, you might have to add a 20mm extension ring. either way, I'd take shots with and without the 20mm ring (in the fisheye dome port) and see which gives better corner sharpness.
remember, with wide-angle lenses, its not just a matter of fitting, its getting the right extension (or no extension) to optimize corner sharpness.
do a search on nodal point for more info on this.
hope this helps

I use the Fisheye Domeport with the extension ring 40 and it works perfect.

One more thing, which zoom gear?
Yes, the fisheye dome port plus the extension ring works just fine. You'll have to modify another gear to make it work. What I did was find one with a larger diameter and shim the inside with padded packing tape to reduce the diameter. I used a Canon 100mm ring and it required several layers of tape. You might be able to find one a little closer to start with.
