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.

        This little diopter works perfectly to correct my vision so I can use the viewfinder without glasses. Attaches easily.

        Puzeling design flaw?

        Comments about Nikon DK-20C +2 Diopter for Rectangular-Style Viewfinder:

        Though I need reading glasses I can still see my camera controls/menu without them, but I rely on resolving focus in my D600 viewfinder. So the DK-20C is the ticket. It goes right on the camera where the rubber eye cup normally attaches, and looks well made with a coated lens element. But there is a problem.

        The outer part of the DK-20C is grooved on the left and right to receive the rubber eye cup, or so it seems. But the regular eye cup, which one removes in order to put this in it's place, would not fit. I was able to get it to fit. But I had to "machine" it. Using sand paper on the eye cup part to make the inner edges (which slide into the side grooves) thinner and a hack saw blade on the DK-20C to widen the receiving grooves, so the regular eye cup would fit on. It makes sense that the option to put the eye cup onto the DK-20C would be there as this is useful. The groove details in the sides of the DK-20C clearly were meant to allow this, or so it would seem.

        I find it rather strange that I had to go to some trouble and some might say to extremes to get the eye cup to fit on. Even without wearing glasses the rubber eye cup, really more of a pad, allows me to rest the viewfinder on my eyebrow area. So I'm glad I was able to alter the DK-20C to receive the standard eye cup, but was annoyed that it was necessary to do it.

          wonder why Nikon makes its VF with so little correction for poor sighed people :-) This helps but for only one owner of the camera.

          Comments about Nikon DK-20C +2 Diopter for Rectangular-Style Viewfinder:

          OK I admit to being older and preferring to wear contacts and reading glasses. But this can really mess up my ability to focus a camera. The Nikon + 2 viewfinder allows me to use the camera direct and see the image perfectly. I know the Camera has auto focus but I want to see what I shoot!

          Excellent Product it just slips on the camera replacing the standard viewfinder and it just takes a few seconds to switch if I am not wearing my contacts.

            Comments about Nikon DK-20C +2 Diopter for Rectangular-Style Viewfinder:

            As a photographer, a significant percentage of the time, I bypass AF/AE and manually adjust the camera's settings, but of course. I purchased the +2 diopter correction eyepiece for my Nikon because, with glasses, I cannot get my eye close enough to the viewfinder to visualize all of the scene it presents. Without glasses, I am forced to seek the "sharpest" blurred focus that I am able to perceive. In conjunction with the camera's built-in -1 to +1 diopter correction, I am now able to precisely achieve sharp viewfinder images. For me, as the song says, "I can see clearly now."

            One should note that this eyepiece IS NOT a rubber eyepiece like that which is furnished with the camera as an accessory. For me, that is not an issue as I am not in the habit of slamming my camera into my face, even in the case of hastily sought action photos. For some, however, it might be an issue.

            By the way, Nikon makes, and B&H stocks, corrective eyepieces that span -5 to +5 diopter correction - a total of -6 to +6 if your Nikon has the built-in -1 to +1 corrective eyepiece, which should accommodate the needs of most.

              a useful tool for aging eyesight, let's me use manual focus lenses again, I forget how good manual focus primes were.
