Before you buy it, it might be worth checking that you're prescription doesn't counter a stigmatism like mine does. AFAIA, these correctors won't help unless you have the lens inside made to correct your specific stigmatism.
Alan - out of interest, where are you buying from?Hi, as a spectacle wearer I am considering buying the DG-2 for my D200. Has anyone got or used one of these? I would be interested in any opinions as to wether it is worth the money (appx £77).
NortherNikon, accepting you are probably not an optician, I would have thought that if you wear contact lenses, then the 2x magnification would not be a problem, only if you wore glasses and took them off for looking through the viewfinder.
