The Canon Optex 200mm t1.8 is a fast, high-quality telephoto prime lens adapted for professional film and digital cinematography. Originally likely a Canon FD mount lens, it has often been rehoused with a PL mount for compatibility with industry-standard cinema cameras. Its wide t1.8 aperture makes it exceptional in low light and allows for a very shallow depth of field, creating a beautiful bokeh effect. The “t” stop (transmission stop) is a more accurate measurement of light transmission through the lens than the f-stop, which is a theoretical calculation. This lens is prized for its sharpness and is a sought-after piece of equipment in the used market.

Fast t1.8 Aperture: Excellent low-light performance and shallow depth of field.
Telephoto Focal Length (200mm): Ideal for capturing distant subjects with a narrow field of view, creating separation and focus on the subject.
High Optical Quality: Known for sharpness and pleasing image rendition.
Often Rehoused for Cinema Use: Many available versions feature robust PL mounts and industry-standard focus and iris gears.
Desirable Bokeh: The wide aperture and optical design contribute to a smooth and aesthetically pleasing out-of-focus background.
