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.

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.

In Topic: Difference b/w old and new Nikkor 105 mm lenses?

10 February 2014 - 04:09 PM

I also own both the new and old versions of the 105mm Micro-nikkor.  I have used the AF-S lens only few times underwater and was put off by the fact that it hunted for the focus point much more often than the older 105mm.  Time and time again, when I was trying to focus at, or near 1:1, it would whiz right past the focus point I wanted.  My attempts to use the new 105 AF-S were on both a Nikon F5 film camera and a Nikon D700.  Newer digital cameras may do a better job with the 105mm AF-S.  The old 105 is a bit slower focusing, but in my experience not slower enough that I missed as many pictures as I missed when the 105 AF-S whizzed past the focus and I had to release the  half-pressed trigger and then try again.  I would expect the 105 AF-S might be better at tracking a moving subject once you achieve focus on it.  The macro lens I use most is Nikon's 70-180 Micro-nikkor zoom which only focuses to .75x.  When I expect that I will be shooting mostly very small subjects that will need more magnification than .75x, I either use the old 105 with extension tubes.  Or more recently, I've played a bit with the 200mm Micro-nikkor in combination with Nikon's T5 or T6 close-up lenses.  The results with that were very sharp.

In Topic: Vacuum Leak Test Update

09 February 2014 - 02:03 AM

If the conditions are very humid and you think you might have condensation problems in your housing, all you have to do is "flush" out the housing with air from your scuba tank just before you close it.  Hold the two housing halves almost together and then blow air into the housing with an air blower that attaches to you LP hose.  Then close the housing quickly and use your vacuum device.
