Nikon DK-20C overview

  • 1Description

The DK-20C -4.0 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.

    Nikon DK-20C reviews

    DK-20C Correction Eyepiece for Rectangular-Style Viewfinder (-4.0) is rated 3.8 out of 5 by 6.
    Rated 5 out of 5 by from Gives me a clearer view of the world! If you need glasses to see far away, this is a great way to get your eye closer to the viewfinder. Field of view doesn't seem to be limited by the lens frame, and it's easy to install and remove. I'd suggest asking your eye doctor (yes, I am one) if these diopter lenses will work for you--if you have too much astigmatism, or your near-sightedness or far-sightedness is beyond the range of these lenses, your image might not be sharp enough for what you need.

    Rated 4 out of 5 by from Does it's job Allows me to work w/o eyeglasses. The built-in diopter adjustment doesn't provide enough range for my eyes. Would like it better if it had the rubber cup that the stock eyepiece has.

    Rated 2 out of 5 by from Mixed feelings.... I have mixied feelings about this correction eyepiece. It does fit the camera and it does correct the eye sight, but you can't put the original eye piece with the rubber cushion over this, it doesn't fit. Without rubber cushion it is not comfortable for me.

    Rated 5 out of 5 by from Works as promised Works as promised. A touch difficult to take off, but then again, this keeps it from coming off inadventantly!
