Canon Cinema Zoom CN20x50, 50-1000mm/T5-8.9 PL

75-1500mm range with built-in 1.5x extender


The Canon 50-1000mm/T5-T8.9 film zoom lens has an outstanding range which is way more than any of the other film lenses in its class and is comparable with the popular CJ45x13, HJ40x10 and HJ18x28 B4 2/3" documentary lenses.

This is the first lens to offer a comparable range to the long documentary lenses previously only available to 2/3″ B4 cameras (such as PMW-500 and PDW-F800) and includes a PL mount compatible with ARRI Amira, RED EPIC, Canon C500 and other similar cameras AND achieves full 4K resolution as well.

Additionally, it also offers a 1.5x range extender, which actually increases the possible range to 1500mm – albeit with an appropriate loss in sensitivity, though worth mentioning that environments where the long range is required would generally be outdoors where there is plenty of light and sensitivity is not an issue.

It is not physically much larger than other zooms and only weights 6.6kg, so it is a perfect complement to Natural History or other productions where portability and range are important considerations.
