Nauticam E-M1 housing, vacuum check system and Olympus E-M1 body for sale

22 February 2017 - 05:22 PM

I have bought the Nauticam housing for the E-M1 ii.  That means I need to sell my E-M1 housing.  The housing is in excellent shape with very few marks, scratches, etc.  Everything works fine.  I will try to get time to take some photos and upload them this weekend if I can.  Housing comes with cap, two O rings, original box and paperwork.


Also have the vacuum check valve for sale, with the pump and wrench.  I will sell the housing with or without the vacuum valve, but I really recommend using one of these whether you get it from me or not. 


I would like to get $1100.00 (USD) for the housing alone or $1200.00 including the vacuum valve, shipped anywhere in the continental 48 states or will ship to Alaska or Hawaii if you want to pay the increased shipping.   


I don’t want to deal with international shipping and payment issues so I don’t want to ship outside of the U.S. at this point.


I will also sell my E-M1.  It is in mint condition, only used in the housing so not a mark on it.  Due to a shoulder injury, I missed almost a year of diving, so not even used as much as it should have been.  $700.00 with two batteries and battery charger, shipped to the 48 states.  If you want the housing, vacuum valve and body, I will discount the package by $100 ($1800.00).

Dome Port Confusion

10 November 2016 - 10:32 AM

I am pretty ignorant of dome port design and theory so to the extent my question reflects ignorance, I apologize.


Nauticam makes a 180mm dome for use with the Olympus 12-40 and 7-14 micro four thirds lenses.  To use that dome for the 12-40 lens, Nauticam suggests using a 47mm adapter and a 20mm extension ring.  For the 7-14 lens, Nauticam suggests using a 55mm adapter alone.


Zen makes a 170mm dome that accommodates these same lenses, but for the 7-14 one needs to use a 60mm adapter and a 20mm extension, while for the 12-40 the 60mm adapter is used alone.


To put this in a simpler format:


Nauticam dome:


12-40 = 67mm distance to dome

7-14 = 55mm distance to dome

            (12mm difference between the two lenses with greater length for 12-40 lens)


Zen dome:


12-40 = 60mm distance to dome

7-14 = 80mm distance to dome

            (20mm difference between the lenses with greater length for 7-14 lens)


I realize these are different size domes but I have been told they have the same curvature and are essentially the same glass.  The adapters and extension rings are all made by Nauticam and so are interchangeable between the dome port brands


How could both of these domes produce similar results with such different lens to dome distances and how can the two companies have such a significant difference in lens to glass distance between the two zoom lenses?)


Does lens to glass distance simply not matter?  Is one of these dome ports "better" because of the differences or is it just a question of physical fit and no optical issues?


Thanks for any help understanding this
