In Topic: Nauticam 45 viewfinder wobble?

01 May 2014 - 05:55 AM

My Nauticam viewfinder also "wobble" slightly when the viewfinders are on the housing above the water.  But when underwater the water pressure, and also the negative internal pressure of my vacuum seal leak detector, seem to hold the viewfinder in place better.  Nauticam uses an o-ring to hold the viewfinder in the housing.  And has two o-rings on the viewfinder "tube".  I believe it is these o-rings that are the cause of the viewfinder wobble.  I've been down to depths of about 200' repeatedly with the Nauticam viewfinder on my Subal ND800, via an adapter, and never had a drop of water get in the housing.

For me the viewfinder choice is a "no contest" issue.  ONLY Nauticam has a diopter adjustment that you can use underwater, which is the place you use the viewfinder, and the right place to make a diopter adjustment.  Because Nauticam has a fairly narrow "tube" throughout the housing to the camera it can be easily adapted to other housings.  I did this first for my previous Seacam D700 housings.  When I switched over to the Subal ND800 housing for my current camera, all I needed to do was work with a machine shop to make a new delrin adapter.  Took only a day and a half.  Much less expensive that buying new viewfinders.

I'm sure we can mount it on one of my D800 bodies in one of my Subal housings.  If we can find a good pool, we can shoot it vs the 14-24 and the 16-35 and the 17-35.  Just takes time and effort.

Doug, 

 

On several other topics I have suggested that you might want to get in touch with me since I also live in Sarasota.  I own a Nikon 14mm f2.8 would be happy to let you borrow it for a few test shots. You can compare it to the 14-24mm zoom if you want.

 

I also own most of the macro lenses you have discussed recently on WetPixel and would be happy to let you try those as well.  

 

I feel trying a lens yourself is far better than just talking about it.  But that requires that you actually get in the water shoot with the lens.  And then take the time evaluate the results for yourself.  And maybe that's just more effort than you are willing to make.  

 

I'm away for a few days but will be back in Sarasota on March 8th.  My phone number is 941 953-7623.

While in Bali last year I took my Subal housing for the D800 to just below 200 ft three or four times with no leaks.
