Leitz SBOOI 50mm viewfinder aero The Mint Instantkon RF70 isThis Leitz SBOOI is possibly the best looking 50mm viewfinder ever made (official Camera Traders opinion). It's tiny and purposeful, and the image is sharp and bright, with clear projected framelines. Even if you don't need a 50mm viewfinder, it's worth having just to look at (official Camera Traders opinion). In excellent condition, with only the most minor cosmetic wear. Includes leather case (which does show some wear.)
