Key Features

The DK-20C -3.0 Correction Eyepiece for Rectangular-Style Viewfinder from Nikon allows you to optimize your SLR/DSLR viewfinder's sharpness in conjunction with your individual eyesight. Nikon SLR/DSLR 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/DSLR 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.

Nikon DK-20C Overview

The DK-20C -3.0 Correction Eyepiece for Rectangular-Style Viewfinder from Nikon allows you to optimize your SLR/DSLR viewfinder's sharpness in conjunction with your individual eyesight. Nikon SLR/DSLR 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/DSLR 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.

What rectangular rubber long cup fits over this ...

What rectangular rubber long cup fits over this -3 diopter? Nikon D3400.
Asked by: Ben
Unfortunately, once the corrective eye replacement is used the original rubber cup will not fit onto the new eye replacement. I was able to modify the original rubber eye piece with a file so that it will slide onto the new eye replacement. It’s tricky.

Does this fit a D7500 or is there one that does? ...

Does this fit a D7500 or is there one that does? My D7500 only goes to -2 and my right eye is -3.5. It's the only camera I have ever owned that I can't use without glasses.
Asked by: Stephen
Yes, this correction eyepiece is compatible with the D7500.

question

I have astigmatism (not near or farsighted -- they're both blurry), and I would really like to be able to photograph without my glasses (the right lens gets pretty oily/smudgy). Would this diopter work if my left eye (dominate eye used for taking photos) was -3.50 (SPH) and 1.75 (CYL). As you can see my eye isn't a perfect sphere. :( Will I still be able to use this and see clearly??
Asked by: Melanie A.
This will help some. Together with the camera diopter it will take care of your spherical prescription, the but will not correct the astigmatism. I also have some astigmatism (less than you) and this diopter did help very well. Be aware though that the rubber eye piece from the camera may not fit well on top of this diopter and you may need to file some plastic away to fit it. i wrote a review on this subject. Good luck.

question

would this piece fit on D5500?
Asked by: Anonymous
I had it on a D7200 -- so I assume it will fit your model. You should be able to go to the Nikon Website and find out for sure.

Does this fit the Nikon D3X?
Asked by: Kent G.
The D3x has a round viewfinder so the answer is no. It will not fit a D3x.

Do you remove the eyepiece on the camera? If yes, how do I do this?

question

Is there a rubber eyecup for this dioptic lens? My camera is Nikon D610.
Asked by: Rui W.
Remove the rubber eye cup that came with your camera. The corrective lens slides into the frame of the view finder. Slide the rubber eyecup on the corrective lens. I had good results checking with my ophthalmologist for advice on which corrective lens to use.

question

Does this fit the D610? If not, what is the magnifying adapter for that model? (Open to using a round-adapter and then screw-in type magnifier.) Thanks
Asked by: Anonymous
The DK-20C is compatible with the D610 as well.
