What is a 100% viewfinder?
A. A viewfinder through which you see approximately what you will get on a slide or negative, thus you see 100% of what you will get in your picture. Nikon Viewfinders for the F4. All non-pro Nikons including the 8008/s and the N90/s bodies, have less than 100% viewfinders; you see less than what you get on the slide or negative. Bodies are described in terms of the percentage you see of what you will get. Thus a viewfinder may be a 90-92% viewfinder, for example. Why aren’t all viewfinders 100%? The pragmatic explanation is that slide mounts and prints crop a bit of the image anyway, so you really don’t need 100% since you don’t really get 100%, and that 100% viewfinders are more expensive to make. 100% viewfinders are generally available only on pro-line bodies in all camera lines.
