I am selling a Nikon magnifying eyepiece DK-21M. This eyepiece magnifies the viewfinder by 1.17x when attached to the viewfinder eyepiece of a single-lens reflex camera. I used it with my SIGMA SD15 and SD1M. I think it's a fairly versatile eyepiece if your camera has a rectangular eyepiece. The condition is excellent, with no noticeable scratches or scuffs, and the view is clear.
