Nikon -2 Diopter for FM3A, FM2, FM, FE2, FE & FA

You Pay: $21.95

Optional Nikon eyepiece diopters allow you to optimize your SLR viewfinder's sharpness in conjunction with your individual eyesight. Nikon SLR cameras (without built-in adjustable eyepiece correction) have a base diopter value of minus one. Minus one is considered the optimum starting point for the majority of SLR users with normal vision. The combination of the camera's viewfinder components and a clear (standard) eyepiece form a virtual image of a subject on the camera's focusing screen that is the approximate equivalent of a viewing distance of one meter.

Each Nikon eyepiece diopter incorporates a numerical value, represented by a minus value (nearsighted) or a plus value (farsighted) number, enabling you to select the appropriate diopter for your vision and your camera model.

The eyepiece's diopter value is, when combined with the viewfinders minus one value, the end-result value. No combination of the camera's base value of minus one and a given accessory diopter's value is required to arrive at the final desired value. In other words, if you require a diopter of plus 3, simply add a plus 3 diopter to your camera.

      Exactly what I needed

          Comments about Nikon -2 Diopter for FM2/FE2/FA:

          I found out that I needed a -2 diopter adjustment based upon my eyeglass prescription. This works perfectly on my Nikon FA and makes the focus screen much more clear when not wearing my glasses. The only gripe I have is that the surface of the ring is hard plastic and could scratch eyewear if not careful. Of course, it's not designed to be used with eyewear, but I find myself using it with and without.
