Press release

Zen Underwater with Olympus 7-14mm and 8mm PRO Lenses

New m4/3 Lenses from Olympus, Ideal for Underwater

Zen Underwater is pleased to announce support for the new Olympus M.Zuiko ED 7-14mm f/2.8 PRO Lens and the Olympus M.Zuiko ED 8mm f/1.8 Fisheye PRO Lens on both the Nauticam N85 mount and Olympus PT-EP Housings.

For Nauticam N85 housings we recommend the following configurations:

Olympus M.Zuiko 7-14mm f/2.8

• Nauticam 36204 N85 to N120 Port Adaptor.
• Nauticam 21120 Extension Ring 20 with Lock.
• Zen Underwater DP-170-N120.

Olympus M.Zuiko 8mm f/1.8 (option #1 - small dome)

• Zen Underwater DP-100-N85 (*see below for additional compatibility).
• Nauticam 36630 Mini Extension Ring 30.

Olympus M.Zuiko 8mm f/1.8 (option #2 - larger dome)

• Zen Underwater DP-170-N85

For Olympus PT-EP housings, we recommend the following configuration:

Olympus M.Zuiko 8mm f/1.8

• Zen Underwater DP-100-EP.
• Zen Underwater ER-EP-25.
• For Olympus PT-EP08 or PT-EP11, add the Zen PA-EP08-EP Adaptor

*The original DP-100-N85 was a two piece design (DP-100-S3 + PA-N85-S3) which is not compatible with the Olympus 8mm f/1.8 as it will cause slight vignetting. The DP-100-N85 was redesigned at the beginning of the year and is now one solid piece. The best way to distinguish between the two is by reading the model on the bottom shade. If it reads “DP-100” or “DP-100-S3” then it is not compatible. If it reads “DP-100-N85” then it is compatible.
