In Topic: Olympus 7-14 mm f2.8 will not fit in Nauticam housings

18 September 2015 - 09:26 PM

Thank you Jack , we had already two  answers from Zen  about the DP-170-N85 first version , that have been published on our board in France :


Sure thing, the DP-170-N85 works with the following lenses:

- Panasonic 7-14mm f/4 plus 30mm extension
- Panasonic 12-35mm f/2.8 plus 30mm extension
- Olympus M.Zuiko 12mm
- Olympus M.Zuiko 8mm f/1.8 PRO
- Olympus 9-18mm f/4-5.6 plus 30mm extension


Thank you for contacting us! Unfortunately, you cannot use the 12-40mm or the 12-50mm with the first version on the DP-170-N85. The reason is the the diameter of the lens is too large to pass through the Nauticam Mini Extension Rings. The DP-170-N85II actually has a larger inner diameter around the port base to allow the fatter lenses to pass through. The 12-50mm zoom gear is also too large in diameter to pass through the mini extension rings from Nauticam. 

That's correct, there is no vignetting with the Olympus M.Zuiko 8mm PRO lens and the DP-170-N85, even in the raw files. The corners are what you can expect from a fisheye lens, still soft, but very manageable when shooting the right subject.

Do you think that the 8mm Olympus fisheye will fit in the Zen DP-170-N85  first version   . That would mean that the 7-14 Pana , 12-50 Oly and  some others could be usable with the dome and a 30 mm extension? One dome only   :)  But I'm afraid that the 8 mm should undergo a little vignetting with the dome 




In Topic: OM-D E-M1 rear dial problem

Unfortunatly I had the same problem with the two kind of EM1 . The older and the newest silver version . Yes you can use the arrow to manage aperture and shutter speed and use the front dial to zoom pictures avoiding to use the rear dial . It's what I'm doing now .You can find the details in the very good book of Darrell Young  " Mastering the Olympus Em1 " available also as a kindle .

Probably several people  will again tell me that I'm completely nuts and don't understand anything to underwater photography  , but strobes are supposed to give light , but also and mainly color and this no larger aperture wil help to show  any color in your work underwater ..especially under 10 m and more ..!!

Thank you everybody for your warm welcome and your help in the improvement of my technical english

.Now , I close this thread for myself as I don't belong to any of these group of people ..:   " This lens is not for everyone and is directed like the rest of the "PRO" line at highness shooters, professional photographers and more."    so no need that I loose anymore my time and yours .

It seems that I get a false information about the weight of the 8 mm and I aopologise for that , but I'm not sure that the 8 mm with an EM1 or EM5 MarkII  could be faster than a Nikon 10, 5 mm with a D7100 or 7200 ...
