Tokyo Koki Tele-Tokina 400mm f6.3 for Canon FD experimental and solid performance throughoutThis Tokyo Koki Tele Tokina 400mm f6. 3 is a classic "big tube" telephoto lens with a nicer build and better optics than most. Focusing is smooth, the manual diaphragm moves well (despite some oil) and optics are clean and clear. Supplied with a Canon FD mount, but this is a T mount lens, so it can be used on pretty much any camera system with the appropriate adapter (sold separately.)
