About Nikon DK-17C

Optional Nikon eyepiece diopters allow you to optimize your SLR viewfinder's sharpness in conjunction with your individual eyesight. Eyepiece diopters are designed for specific camera models and are identified by a plus, a minus or a neutral numeric diopter value.

Standard eyepieces supplied with Nikon SLR cameras have no corrective value and are for dust protection only. Select eyepieces are supplied with a rubber coating designed to lessen scratching of a photographer's eyeglasses.

Nikon SLR cameras (without built-in adjustable eyepiece correction) have a base diopter value of minus one. This is why you won't find an accessory Nikon eyepiece diopter valued at 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 (near-sighted) 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 viewfinder's 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.

Neutral correction eyepieces do not replace the supplied standard eyepiece. The use of a neutral correction eyepiece will change the diopter value of the camera from minus one to zero.

To determine which Nikon diopter value is best suited for you, visit your ophthalmologist, optometrist or dispensing optician. Ask them to determine your diopter from (your corrective prescription) when viewing an object at distance of approximately one meter. Base your selection on this diopter value.

Some Nikon SLR Cameras have built-in adjustable eyepiece correction. Please check your instruction manual to see if additional threaded Nikon eyepiece diopters can be combined with your camera's built-in diopter control. For cameras with built-in diopter control, use additional Nikon eyepiece diopters only if your vision dictates that optimum viewfinder sharpness cannot be achieved with the built-in diopter adjustment control.

Corrects vision

Like to shoot without glasses. This eyepiece does most of the correction and then can fine tune on camera

Great...

I had reached the limit of the eyepiece correction with two of my cameras that prevented getting good focus. After installing the correction lens, this greatly improved focusing ability. Ah.. the pitfalls of aging eyeballs!

I was not quite able to get the built in diopter adjustment perfect so decided to add this eyepiece and then fine tune with the camera's diopter. It works perfectly. I use less diopter on the camera and get clear viewfinder without glasses.

Does the job

By

from Los Angeles

Works fine. The thing to be aware of with these is that the stated diopter value is not the corrective power of the eyepiece itself, but the combined diopter of the eyepiece in combination with the rest of the viewfinder optics.

perfect

By

from Oceanside, Ca.  -  Photo Enthusiast

I had to tear the rubber off of the standard eye piece to unscrew it. Wouldn't budge otherwise. New diopter screwed right in and works perfectly for my vision. Diopter adjustment is now in the center of the adjustment range.

Easy to use, nice to have

Nice to use when you have glasses....just screw this into the finder piece and take off your specs....(provided you are as nearsighted as me) and then camera composing is a lot easier!
