Product Information
If you want to use your lens zoom function while taking photographs underwater, this zoom gear should be used. This Sea & Sea Zoom Gear is used to manually focus the Sigma Macro 70mm F2.8 EX DG lens when used in a Sea & Sea housing for any camera. Sea & Sea precision machined zoom gears are manufactured from either anodized aluminum or durable plastic polymer. Both versions are corrosion resistant. Easy to install in housing.

Frequently Asked Questions
Is the Sea & Sea #31136 a zoom gear or a focus gear?
It is a Focus Gear. Sea & Sea's own compatibility documentation designates part No. 31136 as a Focus Gear used to manually focus the Sigma MACRO 70mm F2.8 EX DG lens inside a Sea & Sea housing, not to operate a zoom function.
What port and base does Focus Gear #31136 require?
Sea & Sea designates the Compact Macro Port 79 (No. 56251) and the NX Compact Macro Base (No. 56201) as the recommended port combination for use with Focus Gear No. 31136 and the Sigma MACRO 70mm F2.8 EX DG lens.
Does this Focus Gear fit both Canon and Nikon versions of the Sigma lens?
Yes. Sea & Sea's compatibility documentation lists Focus Gear No. 31136 as compatible with both the Canon and Nikon mount versions of the Sigma MACRO 70mm F2.8 EX DG lens.
Is Focus Gear No. 31136 still in production?
Sea & Sea's current manual-download page and RDX Nikon compatibility chart no longer list part No. 31136, though we were unable to confirm on the manufacturer's live site whether it has been formally discontinued or replaced. Contact DiveCatalog.com to confirm current availability.
