I have decided to sell my Sony A77 & NEX7 kits and go all in with the Oly E-M1 and Nauticam housing. I feel the E-M1 will fill all of my topside and UW photo needs.

 

My plan is to use the Oly 12-40 PRO, the 60 macro and I already have the 9-18 currently in use on a PEN E-PM1.  I'm hoping the Zen DP 170 n85ii will work not only for the aforementioned lenses, but the Oly 7-14mm PRO when it comes out next year. Anyone given any serious thoughts towards this "new" lens? That would be perfect if it would work on the Zen 170 port...

 

Regards

 

Kent

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.

Hi Phil,

 

Great post on the Oly 12-40mm lens!

 

I am a beginner and am now using an EPM1 in Oly Housing with a 14-42 kit lens and a +7 Diapoter.  I have an EM1 with a 12-40mm F2.8 pro lens and a 60mm Macro lens. Great camera and lens!  I am considering buying a Nauticam housing to use this system underwater. Originally planned to use the 12-50mm lens with the specific Nauticam port. However, this post really aroused my interest in using the 12-40mm in the Zen port instead. 

 

Before making my decision, really want to now how the max magnification of the 12-40mm lens compare with the 14-42 kit lens plus a +7 diapoter. To me, the 14-42 kit lens plus the +7 diaporter is more than enough for my need in shooting macro. If the 12-40mm come close to this combo, I will have no hesitation to go for the 12-40 in the zen dome port.

 

Thanks

DP-170-N85-II is the new version (the one I have) and has an additional 30mm of extension on top of the original. So a total of 60mm of extension, plus the ID of the port body is 77mm allowing the larger diameter lenses such as the Olympus 12-40 or the Sony 10-18 to be used. The DP-170-N85 II is compatible with:
Panasonic 7-14mm f/4
Olympus m.Zuiko 9-18mm f/4-5.6
Panasonic 12-35mm f/2.8
Olympus m.Zuiko 12-40mm f/2.8
Sony 10-18mm f/4 E-mount


Hi Phil,

Thanks for the very informative post reference the zen dome. I have the Nauticam 7" dome which I'm hoping to utilise after a change to the EM-1. From your list on compatible lenses for the ZEN dome above, do you know if those same lenses are suitable to use behind the Nauticam dome as well?

John

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.
