Gates Focus Gear for Sony 16-35 f2.8 GM II

Gear to manually control the zoom function of your Sony 16-35 f/2.8 GM II lens in the Gates underwater housing.

All Flex Gears are designed to adapt DSLR / Mirrorless lenses to Gates housings with Lens Gear Drives, which provide direct diver manual control of such lenses while underwater.  They are ‘Flex’ gears because each covers a range of ~0.1 in / 2.5 mm diameter.  Flex Gears also provide finer focus control with a larger gear diameter than the lens.
