If you’ve been craving the ability to go from 50mm to 1000mm all in one lens, Canon has just what you’re looking for. Announced earlier today, the CINE-SERVO 50–1000mm T5.0–8.9 Ultra-Telephoto Zoom lens is being labeled ‘world’s longest 4K ultra-telephoto zoom lens for large-format single-sensor cameras,” and it comes with a price tag that’s as impressive as its zoom range.
This monster of a lens is designed specifically for use with Canon’s EOS C-series cameras, but considering it’s available in both EF and PL mounts, anyone with a Canon DSLR and deep enough pockets can give it a try.
And 50-1000mm isn’t actually as far as it can go. The lens has a built-in 1.5x magnifier, meaning its true range can be pushed to 75–1500mm.
Here’s a closer look from all angles:
