Nikon Rumors was able to find a bunch of brand new focusing screens designed for the Df camera. The screens, which come from focusingscreen.com, seem to be very similar to those made by Canon since they all state that they were produced using a Canon focusing screen type. They don’t really seem to say very much else though. It overall seems a bit odd as the Nikon Df is stated to have a 100% viewfinder on both Nikon and B&H Photo’s websites. By nature, most cameras with 100% viewfinder can’t have their screens changed.
If these indeed are real though, then they would be designed mostly for use with manual focusing glass as many of them have a split screen that works very much in the same way that older SLR cameras work. But it also means that your subject needs to be centered to be most effective.
We recently reviewed with Nikon Df, and we think that it rocks with classic lenses. Check out our review if you’re interested.
