Product Highlights
  • Fits Select Nikon SLR and DSLR Cameras

The DK-20C -2.0 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.

          Comments about Nikon DK-20C Correction Eyepiece for Rectangular-Style Viewfinder (-2.0):

          It performs its function well, image clarity is excellent, but it does have a few issues one would expect to be absent from any kind of Nikon optics.First, the -2 diopter value seems is questionable, a little math puts it more at a -1 value than a -2. But since other factors could be just as questionable, the actual diopter value would have to be verified by calibrated equipment.Second, the plastic frame quality lacks the Nikon feel, instead it feels cheap in mechanical strength and surface texture.The biggest issue though, is that the rubber eyecup it replaced does not fit over this viewfinder. It goes in 2/3's of the way and no more by any means.The last issue was found instantly after pulling the viewfinder out of it's small plastic bag. A giant thumbprint covering nearly the whole lens was found on one side of the lens surface.In the end, after a few workarounds, this viewfinder worked as expected. The workarounds were:1) Set the camera's diopter adjustment to the min. of -1.7, instead of -0.7 as originally expected.2) Ignore the cheap plastic frame3) Don't use a rubber eyecup over it4) Clean the lens well before installationIt's clear & eyeglass-free camera viewfinding afterwards, as expected.

          Comments about Nikon DK-20C Correction Eyepiece for Rectangular-Style Viewfinder (-2.0):

          I did not even know that these existed for Nikon DSLRs, until I saw them accidentally at Nikon's website. I just thought that those minor dioptre adjustments in the camera were inadequate, and probably I have to wear contacts to use my camera properly!What a difference! I can now read the display at the bottom of the view-finder clearly without my glasses! I can view the display clearly, and actually use the manual focussing accurately!Two words of caution: (1) fit this slowly, firmly and properly the first time before putting in the rubber cup. Because they are so tight, you cannot make further adjustments later on. Remove the rubber cup by sliding up, Clean the channels on two sides, the glass on the camera-body before putting it on. Finally clean the rubber eyepiece, to be put on last. (2) Have your eyes checked at an optometrist recently, decide which eye you will be always using, then buy one (+3,+2,+1,-1,-2,-3) with the closest power. If your eyes have higher power, you might fit two, one after the other - it works! Finally, if you have high cylindrical, then contacts might be the only option for you.They are cheaper at B&H than at Nikon's website!

                    I use this product with my Cosina C1s and Voigtlander VSL43 single lens reflex cameras. (Viewfinder accessories that fit the Nikon FM10 camera also fit these cameras.)

                    Due to my age (80 years) focusing a SLR camera is becoming increasingly difficult. This -2 diopter is just what I needed to help with that.

                                Optically, it solved my problem with the diopter adjustment on my D200 not going far enough to see without my glasses (I'm near sighted). It fits nice and snug on my D200 but the original rubber part this replaces doesn't fit in the gloove of this eyepiece. I have an olympus E410 and the rubber eyepiece from it fit this diopter so be aware, at least on a D200 the original eyecupthingie won't fit on this.

                                    I purchased two of these, one for my D50, one for my D200 as I have to wear bifocals & finding the "sweet spot" to focus can be a bit trying. Both slipped easily on the intended cameras & improved my ability to achieve focus greatly. One thing tho--there always is one thing--the diopter piece will not slip into a Nikon DK-21m magnifying eyepiece. If you are nearsighted this is recommended
