good to hear you are happy with your bid!
The extension should be part of the macro setup.
It was used between the camera and lens, the frame was for the distance, no focusing, just get the thing between the vertical parts and thats it...
Different tubes for different magnification ;-))
The viewfinder is not so exact like a dslr or a electronic one, its more a reference....
The scubawinder converts the 35mm into a ~ 17mm, so its close.....
An original one is sometimes to find on ebay, but will cost the same as your whole setup ;-))
thanks, yes the viewfinder im sure will be fine, and yes its is just an estimate, but i need to check, it seems like the previous owner used it with the 15mm surely! its such a well kept and organised case full of stuff im suprised the nikonos one isnt in there.
and it even has an unopened set of O rings!
I also have a flat disc of white plastic that i assume is a diffuser for the strobe. but i cant seem to work out how to attach it. its says on it ' 15 wide adapter' and two small holes either side, and an indication to increase or decrease the aperture by 2 stops?
anyway im gonna get it serviced in london, just to make sure.
