Nikon 2932 Overview

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.

I used this on my F2 Nikon film camera, excellent fit, appears to be genuine Nikon and works great for those of us needing a vision correction with our old film cameras.

Relief for old eyes

First, let me say that I bought this to use on a Nikkormat FT2, on which it fits perfectly. After reading reviews, one reviewer convinced me that this would work, as he noted his use of +2.0 or 2.5 diopters for his readers. Since I also use this correction, I went with +1 (+2 stronger than camera default of -1). Now I can see focus screen almost perfectly without glasses! It should be noted that the Nikon FM does not have a screw off eyepiece, but a permanently mounted eyepiece. I don't know about other FM's, FE's, etc.

I bought this lens and also a +2 D version ( to attempt future proofing ) for my Fuji X - Pro 1. Fuji no longer do these and it is impossible to find these new in New Zealand also Nikon lenses. Lucky for me that B.H. still had some Nikon FM2 lenses which are an exact fit. Saves me from having a NZ$3,500 paper weight. The +1D is just right at the moment and I have a +2D if my eyes change much in the future. Thanks B.H. Mike Cassidy

High quality glass diopter

I bought the +1 diopter for a Nikon FE, a camera that does not have an adjustable diopter. It works perfectly. Optics are high quality with no distortion out to the corners of the viewing area. No longer do I need to use reading glasses to focus using this camera, greatly adding to the enjoyment.

Very useful

If you need a +1 reading glass and your camera does not have diopter, you need it. Make sure the size is right. I use it for my Fuji X-Pro1 and it's perfect.

Diopter for Fuji X Pro 1

Well make Nikon product. With stock Fuji diopter the OVF on the X Pro 1 is clear and the EVF is alittle fuzzy. With this +1 Nikon it is the opposite. I am ordering the +2 to solve my issue.

Fits F2!

Works perfectly! Even though it doesn't say this in the title of the item, it does thread perfectly onto my Nikon F2

From info on line, had impression the + series diopters were helpful for for us farsighted types. Not in this case. The +1.00 diopter no improvement on my FM, actually degraded image. Maybe I got it wrong & ordered incorrectly. The diopter itself in good shape, just doesn't work for me.
