Wanted: Pentax Diopter Correction Lens Adapter M +2

My old eyes need some help. My +1 adapter is getting a bit weak for me.

(Also happen to have a -3 which is no use to me, in case anyone's interested in buying it?)

Hi, if this adapter is still available? I put the diopter lever on K20D on the most right position and still not work. I dont know which one is suitable? The -3 one or the +1 one?

Thanks,

Robert

If you want to buy one, contact SRS to see if they are still available. I suspect they may be.
