- Nikon DK-20C Diopter Eyepiece Correction
Optimize your SLR/DSLR viewfinder's sharpness with Nikon DK-20C Diopter Eyepiece Correction. DSLR’s without adjustable eyepiece correctionhave a default -1 base dioptre value which is considered the starting point for users with normal vision. Eyepiece corrections will allow you to get the best viewer eyesight depending on the dioptre value. Negative values are for nearsighted while positive values are for farsighted. Each dioptre value provides appropriate equivalent to give shooter’s their ideal sharpness. Nikon DK-20C is available in values of -5, -3, -2, 0, +0.5, +1, +2, and +3. They are compatible with select Nikon SLR/DSLRs.
Product Features in Detail
Easy-to-use viewing and focusing aid
An easy-to-use viewing and focusing aid which allows near and farsighted photographers to view the finder image accurately without wearing eyeglasses.
Optimize your SLR viewfinder’s sharpness
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.
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.
Neutral correction eyepieces
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.
Built-in diopter control
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.
Correction lens, +3.0 strength. An easy-to-use viewing and focusing aid which allows near and farsighted photographers to view the finder image accurately without wearing eyeglasses.
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.
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.
Determine your diopter value
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.
Select camera models will accept eyepieces from multiple eyepiece families. Used for F-301 / 401 / 501 / 601 / M, FG, FG-20, EM, F80,F70 / F75 / 65 / 60 / 55 / 50, FM10, FE10, Pronea S / 600i, D40, D40x, D60, D70, D80, D90, D100, D200, D300.
