Our universal Zoom/Focus Gear and lens clamp set works with larger lenses
with Zoom/Focus Gear rings up to 2.8 inches (71mm) in diameter. Our unique sleeve
and clamp design represents the most universal and affordable zoom
gearing system in the underwater photography industry.
The shorter 7/8 inch length is designed specifically for use with the
port mount featured on most Ikelite compact mirrorless and compact DSLR
housings. Refer to the appropriate Lens Port Chart for recommendations
regarding lens compatibility.
