touit

Rarely used Zeiss Touit 50mm f/2.8M Macro Lens (Sony E-Mount) for sale including box and all accessories. Front Lens Cap Rear Lens Cap Lens Hood Looks mint, no scratches or dings. Fair Price $550 including insured shipping withing the US.

so I am prepping for a dive with my trusty nex 7 and have just recently received the touit 50 mm. It has the updated firmware but still seems amazingly slow to focus. How is its usability under water? Does it focus faster with the a6000? Is there a way with the Nauticam housing to manual focus...
