Hi

the 15mm UW lens is not like a 15mm in air, more like a 20mm on an SLR - not stupidly wide at all, in fact exactly what you need and very esy to handle. Let me know if you are interested. Mine is only for sale because I have changed to digital.

I see, what sort of price you looking at????????????

Thanks for all your help! It's all just a matter of money for me. Hiring is out of the question - I might as well buy a lens for my Nikonos and a decent digital is 1,000s of pounds. So as an entry point I went for the Nikonos. I've learnt a lot - and yes it is expensive with processing, but there isn't much you can do when you don't have upfront cash.

Yes I will be scanning these negs and working on them in photoshop. I hope to fine print them afterwards too.

As for these lens' the 15mm sounds stupid wide - but how much you looking for?

And the 20mm???

If you would prefer to talk money privately - email me on cborkett@hotmail.com

I seeeeeeeeeee.... so it would be best to be shooting on a 28mm if not 20mm lens... my subjects are gonna get big too... hmmm, this would account for a lot in colour issues that I have been having!!! I knew I should have shot b/w....


Someone told me today I would always struggle with my Nikonos. They recommended the best equipment for film based work to be a Nikon F5 in casing. Is this really the case. I think the Nikonos has been giving me OK results so far it has limitations, but you can find solutions.

Anyone want to sell me a 20mm Nikonos lens!!!????

Water acts as a filter so you want to minimize camera to subject distance. Shoot from 1 foot to 1 meter away and no more. Even at 2 meters you will see a significant change in color - though at this range it can be adjusted a bit with filtration when printing.
You will see that many people on this board use a fisheye lens for much if not most of their work. It allows them to get very close and still have a wide angle of view.
Underwater photography has several limitations, you have just discovered one of the major ones. ;)

there is just no way to meter the light from above water, you will need to use the on camera meter or a Sekonic.

Are you shooting with a 15mm? Strobes?
I would just set the shutter dial to A, which is aperture priority. Let the camera figure out your shutter speed for you. Then bracket your exposures from f4 all the way to f8 or f11, including the half stops between the full stops.
Then move your ISO dial to the next setting, either up or down depending on which way you would like to expose it, and then bracket your fstops again.

That way you will have about 4 or 5 shots per ISO setting, one of them should come out right...


I can't use strobes where I am working hence why I was asking the 'ambient' questions. I think I will try working on Aperture priority working on the lowest shutter speed possible to get the smallest aperture hence greater depth of field and so hopefully, get sharper pictures... as for this blue issue, I think I can't work any further away then 2 meters... that's OK, but not great!!!

I have to say though the ambient readings I have been making above the water have been helping as a rule of thumb, but obviously not very consistent as if I move direction etc the light is going to change...
