I just posted this in dpReview. But why should they get all the fun? There have been several threads where people have asked about fitting a D70 with a split image screen or a "bright screen" or something other than the stock screen. Tonight, I learned that this is not just possible, it's actually fairly easy. In the D70 mirror box, there's a spring that runs around the front edge and both side edges of the viewfinder. It has a bend in it in the front, forming a protrusion that you can hook with a small screwdriver. Press this protrusion inwards, into the camera, and the spring unlatches from a black plastic projection at the front of the mirror chamber, and the spring hinges downward, then the focusing screen holder also hinges downward. With flat bladed tweezers, you now can slide the entire focusing screen out of the camera. The screen is small, a DX sized screen, so you can't simply pop in a split image Nikon FM3A screen or a Beattie IntenScreen for an F100. You'd have to measure the original D70 screen, and then mill the new screen down to fit. I'm going to give it a try later this week.
