Title: Very disappointing!
Review: I bought this initially with for my D40 and recently tried on my D300. The optics are small and restricting cutting one's field of view with eye glasses. I gave it a 1 star because Nikon did not do their best buy took shortcuts. It can be made properly and yes it would cost $50.00 but it would be a big hit and improve your viewing image. As it stands a total waste of money.
