Hello all

 

I am wondering if anyone has actual UW experience with this lens. I have owned it for years and have never taken it underwater. It generally gets mixed reviews topside.

 

I am thinking Seacam Superdome.

Any suggestions on diopters or dome extensions?

 

I have recently bought the Nikon 8-15 FE and will be taking this and the dome to Kimbe. I though this would be a great compact topside lens that could be pressed into UW service if suitable.

Back in the day when I shot with film (Nikon F3 and F4), my three primary lens for wide angle work were my Nikon 24 f2, 18 f2.8 and 16mm fisheye. For big animals like sharks, sea turtles, etc., was the Nikon 24mm, for reef and wreck (with and without divers)and splits it was the 18mm behind a 8-inch dome port with a 20mm extension ring. It worked really back than, as I produced a lot of covers for both Skin Diver and Sport Diver magazine. Nowadays, find that that are several newer model wide angle zooms from both Nikon and Tokina that work even better optically than that lens.

Thanks Walt,

 

That is very helpful, indeed. Do you recall if you used a diopter? I'm guessing yes.

 

I am going to use it with a superdome, so hopefully it will be a little sharper at the edges. Thinking it should also be good for splits.

 

I will try it in the pool once I sort the diopter issue.

I had an earlier version of that lens. It worked fine on my FE2 in an Ikelite housing with a small dome port.
But that info is 30 years out of date.

No diopter's were used with either the 18mm or the 24mm, just simply (through a little bit of trial and error) figured out the distance the port needed to be in front of the lens. I am sure with a Seacam Supperdome little (10mm, 20mm at the most) to no extensions will be needed.

I used this lens a while back but on the DX format. Sold it before getting an FX camera. I used it mainly with a WP and a diopter to allow closer focusing.

 

From some old (> 10 years old) Seacam data: Harald (from price list) has the 18D and SD used with no PVL whereas Stephen Frink (from his website) shows a PVL25. This may have been before the PVL20 came out. Reading this info off my old computer (not the one being used right now).

 

ps. I had this lens at the same time that I had the RS 18mm lens. Looking at both at both ends (front and back) they appeared identical to me. I was not happy about this (the RS lens) as I was expecting a relatively compact water contact optic rather than what I got, which was a dedicated 8" hemispherical port and topside lens. It was OK on film.

 

I used it for this shot:

I to shot that lens a lot with film (f3) as well as the 24mm. No diopters. I had custom extension rings made for each lens with my aquatic housings. I worked the specs thru a guy at Nikon back in the day on finding the exact extension length . There where 4 of us that had all the same gear and made 4 sets of rings one for each for these lens-15mm-18mm 24mm 28mm and a 35mm.

 

switched to Subals in the F5 days

Thanks all

 

Just got out of the pool

 

Tested with SD, +/- 20mm extension, +/- +2 diopter

 

Looks sharpest with 20mm extension and no diopter.
