Leitz SBOOI 50mm viewfinder brand_Panasonic This SF-1N is in excellentThis 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.
