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.

        Comments about Nikon DK-20C +1 Diopter for Rectangular-Style Viewfinder:

        Diopter adjustment on the camera itself was a little out of range for my eye(s). This, in combo with the built adjuster made, every thing perfectly clear (focused).

          Comments about Nikon DK-20C +1 Diopter for Rectangular-Style Viewfinder:

          I purchased a used Nikon D300 in excellent condition with one exception. The diopter adjustment on the viewfinder did not work and I could not get a sharp finder image with my glasses. I did some experimenting and found I needed +1diopter correction. The +1 diopter correction lens works perfectly giving a clear sharp viewfinder.

          Comments about Nikon DK-20C +1 Diopter for Rectangular-Style Viewfinder:

          Slots at side of the diopter need to be filed slightly as they are way too thin and do not fit onto the D80 or D60 without extreme pressure. Forget removal. They need to be "re-slotted" with a file or sandpaper to fit properly. I bought a +1 and a +.5 diopter for a D60 and a D80.

          Comments about Nikon DK-20C +1 Diopter for Rectangular-Style Viewfinder:

          Works as advertised, however, NIKON need to control manufacturing better. The (2) grooves located at the sides of the diopter and too small. About .030" too small. Unless you have the strength of SUPERMAN, you will have an extremely difficult time getting this device attached. Removal? Don't even think about it. Once it's on - that's it. I bought two and tried each on my D60 and D80. I small filing of the grooves made them usable. NIKON, please fix this defect in manufacture.

          Good product but not for me.
          Thinking that I use +1 reading glasses I purchased this viewfinder but I can't see or focus anything.
          The product if perfect but not for me.
          I believe I made a mistake but it is my fault,
