Peter, you probably know that the eyepiece is already at -1.Pentax made som smc diopter correction adapters suitable for the viewfinder eyepiece of the LX, ME, ME-super .... Anybody knows if they are still in stock somewhere. I need -2.5.Peter Smekal
With the Spotmatic, you could have a piece of glass made by an optician and put into a special eyepiece. I don't know if there is such an item for the M eyepiece. Maybe the list could tell you if this adapter does or does not exist. If it does this would be the most confortable option.
