Hi Everyone, I have a well taken care of CANON FD 400mm F2.8 PL mount, collimated and converted with focus gear by Duclos Lenses-USA, for sale. It also comes with 2x extender. Tested to cover 8K Red Raptor sensor. Time for me to find a new home for it as it's under utilised. Abit of trivia, this charming lens with optical character is more than 30 years old and has even seen some battles in the African safari;-) Items in the package, 1. 400mm f.2.8 lens 2. Opitex 2x converter- making this lens a 800mm! 3. Lens Hood 4. LENSCOAT front Lens cover 5. Steel Shipping case 6. Rear drop in filters Has been tested to work on RED 8k VV sensor without any vignette. let me know if you need more info:)
