Tokina 500mm f8 RMC with Doubler extender - Contax Yashica

Mirror Tele lens - Contax Yashica mount - will fit pretty much any modern camera via adapter. Comes with RMC Tokina Doubler (sn 8201067) which transforms this into a 1000mm lens!!! We test shot it on a very dark and grey December 2024 -- on a Fuji GFX 100 megapixels camera -- see photos. The ones with vignette are with the doubler = 1000mm, the rest are "just" 500mm. The doubler/1000mm will not vignette on a full frame sensor (the Fuji is medium format).
