In Topic: Am I going soft: Nikkor 16-35mm

Dear Diver Doug,


Perhaps no one has "weighed in" with any results on the comparison of the two lenses, because like you they were unwilling to make the effort to do the work a good comparison involves.  I have repeatedly offered to lend you lenses that you have expressed interest in so you could test them yourself, including offering to lend you my Nikon 14mm f2.8 to test. And you have never taken me up on the offer despite the fact that like you, I live in Sarasota.

The easy way to prevent losing a camera and housing to Davey Jones is to add a little floatation to the housing so that if you drop it or get it knocked out of your hands, it slowly floats upward to the surface.  With a little testing you can add just enough buoyancy so that the housing doesn't impede your swimming.  



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.



In Topic: Viewfinder comparisons

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.  



In Topic: Nikon 14mm f/2.8 prime

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.
