In Topic: Olympus 12-40 F/2.8 and the Zen Underwater DP 170 n85 port

The short answer is yes, the Nauticam port chart recommends the 7" acrylic for the Olympus 12-40mm and the Sony 10-18mm, the other lenses show the 6" Nauticam port but should work well in the 7" port. They also just released a new port adapter and extension for the Nauticam 180mm optical glass port for these lenses. I still would recommend the ZEN DP 170n85II port for anyone wishing to go with optical glass.

You would be correct in regard to the extensions not being "new". What you have is an adaptor that allows you to use the ports designed for the DSLR systems with the 120mm port mount. So you would be using an existing gear for the Panasonic 7-14 and 12-40 with the zoom knob on the housing or the new gear for those lenses which operates off of the knob on the adaptor. The 20mm port extension used with the 180mm glass port for the listed lenses would also be different than the current extension as well, it would now be 120mm to fit between the 120mm end of the adaptor and the 120mm opening on the port. The 12-40mm would be mounted from the front of the housing after the adaptor is in place and then the port would be mounted over the lens. This is because the 12-40 is to fat to fit into the housing mounted to the camera. When the new Olympus 7-14 F/2.8 zoom comes next year (or 2016) it will probably need to be mounted the same way.

 

The new ZEN Underwater DP 170 n85II works much the same way except without the adapter and 20mm extension which is built-in. It mounts over the 12-40mm F/2.8 zoom in the same way.

If the Olympus 7-14mm F/2.8 PRO lens has the same excellent quality as the 12-40mm pro I think you will see a bunch of E-M1 users wanting one.

Reef has been doing retro fits of the Nauticam vacuum system in the E-M5 housings and it is a tight fit but works quite well. I have not seen the Backscatter vacuum system so would not want to comment on how well suited it may be for the EM5 housing. You can find my review of the Nauticam vacuum system in a back issue of uwpmag.com
