Optional Nikon eyepiece diopters allow you to optimize your SLR viewfinder's sharpness in conjunction with your individual eyesight. Nikon SLR 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 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 +1 Diopter for FM2/FE2/FA:

        This diopter is necessary in a camera that doesn't have autofocus or a viewfinder adjuster that matches your visual impairment. As I got older I found that I needed help from glasses for reading and distance. It's a pain to look through the viewfinder with glasses on - with this diopter everything is clear which makes focusing easier. I looked forward to receiving this and I have not been disapointed.

        Comments about Nikon +1 Diopter for FM2/FE2/FA:

        This lens works with your normal distance glasses use 1 diopter less than your reading script calls for. Example My near vision was a +2 so I just ordered a +1 for the camera and every thing is in good focus. If I had ordered the +2 it would be out of focus.

        Well, needed a a diopter (+1) for my Fuji XPRO1 in 19mm size...works perfect and I am very happy! I understand Fuji is coming with there on series at a good price - kind of late...Any 19mm for your specific correction power will work on the Fuji. This Nikon series (NOS) are still available and they are great.

        Fits Fuji X-Pro 1 Perfectly

              I bought one of these to use with my new Fuji X-Pro 1. It fits perfectly, does what it is supposed to do, and costs less than others. Other than a built-in diopter, what more could one want?

                  No thanks to Fuji the X-Pro1 does not have a diopter adjustment. The manual tells you to contact Cosina but in North America it's not a popular item. After searching a few blogs I found what I needed but e B A Y was no help for a +1.0 so I was glad to see that my friends @ B&H had stock and the service to Canada was very quick and it arrived in perfect condition.

                  Viewfinder diopter for Fuji X-Pro 1

                    Comments about Nikon +1 Diopter for FM2/FE2/FA:

                    Unlike most other cameras with viewfinders, the Fuji X-Pro 1 does not come with a built in adjustable diopter. This is a problem for glasses wears, but is also a problem for anyone older than 45 due to senile presbyopia, even if they otherwise have perfect vision. There must be something about the 2-focal length viewfinder in the X-Pro 1 that does not allow for an adjustable diopter, as its sister camera has one (Fuji X100) and Fuji must know that the most likely consumer of this expensive retro camera will likely be in the age range affected by presbyopia.

                    Like most folks, I know the presbyopia correction I need for reading glasses (+1.75 to +2.25), but I had no idea what I needed for the X-Pro 1. An internet search suggested that camera viewfinders have a built in diopter correction of -1.00, and so a user's reading prescription might not translate directly to the correct viewfinder adjustment. To make matters more complicated, the Fuji X-Pro 1 has a combination optical and electronic viewfinder, so any diopter correction has to allow for the short-distance EVF viewing while at the same time not blurring the long-distance OVF. It all sounded quite complicated, so I purchased both the +1 and +2 diopters by mail order. I found that both worked well for the EVF (+1 was very good for the EVF and the +2 was great for the EVF), but only the +1 was good for the OVF (+2 was blurry).

                    Again, for me, the OVF is sharp without glasses, as I have only senile presbyopia and do not wear glasses for distance. My prescription is in the +2 range for reading, and the +1 Nikon diopter was the best compromise that allowed sharp viewing for both OVF and EVF. If I used only the EVF, I would install the +2 diopter, as this produced a WOW EVF image for me, but I wanted to preserve the use of the OVF, so I picked +1. The diopters are cheap enough, so I am keeping both, as they each has their own advantages, and who knows, I might need the +2 in a few years as my presbyopia worsens with age.

                    I hope this helps prospective buyers.

                              The age old problem I speak of is when one's age is becoming 'old.' The view through the eye piece of my X Pro-1 was a bit fuzzy, not due to a flaw in the camera but due to a flaw in my eye. . . old age creep.

                              This diopter fit perfectly and completly nipped the fuzziness right in the bud. Problem solved!
