I bought this because I was tired of having to deal with looking through the viewfinder of my D300 with my glasses. I was not able to see the whole viewfinder with my glasses on, plus I was scratching up my glasses and it was uncomfortable. Now I can easily take pics without my glasses. I wish I had bought this a long time ago. This is highly recommended to anyone who wears eyeglasses. The only thing that may be a problem is the eyecup for the D300 is a tight fit over the eyepiece.

I bought this diopter attachment for a Vivitar V3800N camera, not the Nikon cameras it was made for. I thought that the Nikon FM10 might be close enough to let me use diopters made for it. It doesn't fit tightly, but it does work well enough that I can now take pictures without having to wear my glasses.
