Canon FD 50-300: The Final FD 

In 1982 Canon released its last lens off the FD production line, and they did not disappoint. The 50-300 f/4.5 L was Canon’s first super zoom with a 6x ratio. They used 2 special UD low dispersion/low diffraction elements to control chromatic abberations in their 16 element/13 group design. Canon’s original 4 group optical system meant this lens was rather simple to service and therefore a good candidate for rehousing.
Genuine Canon S.S.C. coatings ensure this full frame zoom will match well with Canon K35 and FD prime lenses...making it the prefect companion to these popular lens sets. However, thanks to its character rich image, the Canon FD 50-300 will also cut together well with any vintage lens sets from the 70’s and 80’s (Leica R, Olympus OM, Nikon, etc.) The bold flares, pleasant bokeh, and gentle fall off make this zoom lens a much needed addition to any rental house.
The image circle generously covers Arri Alexa LF open gate throughout its entire zoom range. Focus and zoom functions are both internal, so there are no telescoping or rotating parts to get in the way of support gear. Close focus has been greatly improved from 2.5m to just 1.8m (6 ft.), and the front diameter of the lens measures 136mm diameter. The original 8 blade iris has been replaced with a 15 blade circular iris. The stainless steel PL mount is interchangeable between LPL, EF, or E mount. Lens support is built in to the lens and has a threaded 1/4 20 mounting point for secure stability.
