==== Summary ====
The Canon 85-300mm FD, introduced in the mid-1970s, is a vintage full-frame zoom lens offering a 3.5x range from standard to telephoto. Known for sharp central rendering, textured bokeh, and artistic flares, it features ED glass to minimize chromatic aberrations. Modern rehousing adds a 15-blade circular iris, PL mount, 0.8 module gears, improved close focus, and parfocal precision, blending its vintage optical character with contemporary cinema functionality.
