Rare 135mm Tele-Lens A 135mm 1:2.8 lens. Tokyo Koki Mount??? I am here trying to find the appriopriate adapter for this 135mm Minetar lens. If anyone knows anything about this pre-cursor to the T-Mount hit me up in the comments or my Facebook page here . The seller states its a 49.2mm/1-15/16" Tokyo Koki mount. Used by Soligor, Sun, Tokyo Koko, Vemar, and other lens manufacturers. Adapters have been seen for Minolta MD, M42, and Nikon cameras. Preferably I am looking for an adapter in the M42 range since I have a M42-EOS adapter. You can view more mount photos here in this folder on Mediafire. http://www.mediafire.com/folder/mflhi6x9bo218/Lenses Source: eBay Listing
