Eyesight correction tip for R-D1
I bought the Nikon correction lens for the FM, which fits the R-D1.
When you order the lens, there's one thing to watch out for... the diopter number of the lens is not the true strength... Nikon allow about -1 diopter for their viewfinders (reflex cameras often have the focussing screen at a virtual distance of 1 meter)
So for example, I take -2.75 specs, but a Nikon -3 isn't strong enough! I need a -4 for the Epson. This is because RF finders are focussed at true infinity.
When you order your lens, subtract one diopter from you prescription. I'm still waiting for the replacement!
