In Topic: Any hands on experience with Nikkor 20mm 2.8D ?

23 March 2017 - 04:57 AM

 I understand that this isn't the ideal lens to go buy for UW photography, or the most popular choice for focal length (and fixed on top of it).

I really don't know why. I find fixed focal length lenses make you really think a lot more about how you shoot. I've used 20s, 24s and 35s underwater and I'm thinking about using a 28 in the near future. Many are excellent lenses and can be set up to be very good underwater. Limiting, perhaps but actually are (as above water) a very good discipline, and can give a better appreciation of how to use a specific focal length (and FWIW I've not shot on a zoom for about 5 years below or above water and I do think that this has improved my photography).

Caveat - I-ts a long time since I used a 20mm f/2.8D Nikkor underwater but I used to and I liked it well enough and it should still work well enough if situated correctly behind a reasonably sized dome port (Seacam, which I supply, certainly suggest that it is ok behind both the WidePort and Superdome, and I'd guess it will work ok behind the CompatPort too). Basically a lens with a 90 degree field of view is about the limit of what used to be considered viable - in the (film) days when smaller domes were more the norm - although often they were used with diopters behind smaller ports. Today we are more critical but you should be able to get it to work well enough. If its not 'supported'-  I assume that simply means that there is no recommended port/extender combination - this is possibly because fewer people use fixed focal length lenses these days and little data is available (I'm surprised nobody who uses one has posted). On the Seacam it simply sits behind the port with no extension and this is where I would start. Personally I prefer fixed focal length lenses and would happily use this 20mm lens if I shot on Nikon - Canon's offering has not impressed me above, let alone below water!

Forgot to say - if anyone wants the housing without the camera I'm happy to sell the housing alone.

I thought about it and have now rewired this housing so that it now has 2 x Nikonos 5 type flash connectors, and the sockets are clean and working well, as I thought that this might be more useful to many. So needs a check - pressure test (looks like a quarry dive!). I should have said that condition overall is good - some signs of use but nothing of any significance - and I've oiled it yesterday too. Complete with spare 'O' ring set (actually 2 x main 'O' rings) tools and neoprene pouch. If anyone wants photos, pm or email me.

OK. I've added a GPro viewfinder and a scratched and trashed (but about usable) Flat Port (will measure and add info), and I've realised it has 3 x S6 connectors (I can swap for 2 x Nik5 though if required). Same price (£1800) including camera. So 'ready to go' - I've used this housing for pool photography of kiddies and parents (add a 35/1.4 + PVL35 + Superdome and it will produce superb shot) and its had very little seawater time so far.
