Nikonos Nikon R-UW 13mm Lens Repair

13 July 2016 - 10:45 AM

Does anyone know of a repair facility that could clean, and repair the coating on the rear element of this lens. Or better yet replace it.


May be corrosion of the coating or less likely fungus. It's not on the L37C filter


Its in otherwise excellent condition.


It's too old for Nikon to be bothered with it:(



Nikonos 105 Strobes and cables

31 December 2015 - 02:01 PM

Happy New Year to all!


My New Year resolution is to clear out old gear not being used anymore:)


I have for sale:


2) Nikonos 105 strobes, like new condition, includes all caps and diffusers. O rings stored separately. Never flooded.

     Includes ULCS ball adapters. $130 each, $250 for both.


2) Nikonos sync cables. Like new, never flooded. $50 each


2) Nikonos double sync cables. Like new, never flooded. $80 each


Pictures as requested, but they look like all other Nikonos strobes and cables.


Items in Vernon, BC Canada





Viewfinder Setup

28 November 2015 - 09:49 AM

Can anyone help with this?


My imaging chain is as follows:


Myopic eye -> single vision, -2.5 corrective lens in right side of mask -> Nauticam V/F with diopter adjustment -> camera V/F with diopter adjustment -> lens -> port -> water


My vision is good close up with no correction, so I need my left eye to see the camera back monitor and controls. My accommodation is very poor closeup with corrective lenses.


My questions are:


(1) Is there an optimal way of setting this up, given 2 adjustment points (camera V/F and Nauticam V/F)


(2) Do you have any suggestions re: bifocal lenses for mask. I would love to have corrected vision and still be able to see the camera controls.


Thanks in advance:)



Sony A7 Nikonos 15mm Test Image

04 October 2015 - 07:42 AM

I took this in a pool a few weeks ago:


Sony A7, Nauticam NA-A7, Nauticam 180 viewfinder, Nikonos 15mm

Apparent distance 1 foot (measured), f/11, 160 second, Manual Mode, Auto ISO @ 200

Focused with Focus Peaking.


I was looking for corner sharpness with rectilinear lens, avoiding use of a large dome.

(I had a little trouble getting the target flat due to spacing of the suction cups vs grout lines. The grout in the corners may be the best indicator of sharpness.

I can't post a JPEG larger than 1000kb)


I was looking for a relatively lightweight,  rectilinear wide angle travel rig.


The orange discolouration is sunlight filtered through forest fire smoke, filtered through pool water:(


Looking for opinions, suggestions, comments and discussion:)
