The new 21/25 Viewfinder from Voigtlander obsolesces the need to carry around a bag of viewfinders for your wide-angle needs. Its two sets of framelines replace the 21mm and 25mm prime finders. It is just as bright as its predecessors, and just as well built. Cosina is a true innovator.
This version of the 21/25 Viewfinder is made with a silver chrome finish. It will look nice on a Leica M2, M3, or MP.
