Does anyone have any experience with the Sigma 17-70 /2.8-4 DC Macro OS HSM lens behind the Sea & Sea fisheye dome 240? The Sea & Sea port chart says it only needs a 20mm extension ring, and I would like to find out if that's really the case. Most other dome/housing combos that refer to this lens indicate the need for at least a 40mm extension.
Thanks for your insight!
