RARE, very hard-to-find Schneider M-Componon 50mm f4 lens for macro/close-up photography.  This lens is threaded to mount in a #0 shutter. It features an aperture range of f4 - f32, a reproduction ratio of 2:1 - 12:1 (Schneider lens catalog specs), covers 4" x 5" and is extremely sharp.  If you require a shutter, at the time of this initial listing I have a couple available, sold separately. Please inquire if interested.  This particular lens is a Linhof hand-selected item, so it is of the highest quality. Ships via USPS Priority Mail.
