Description — ARRI 100mm T1.9
The ARRI Master Anamorphic 100mm T1.9 is a professional cinema prime built for the demands of high-end motion picture production. Designed around the industry-standard PL Mount, it integrates seamlessly into Cinema / Video camera systems and delivers coverage across the Super 35 format. The T1.9 maximum aperture — expressed as a T-stop to reflect actual light transmission — provides meaningful light-gathering capability for a telephoto prime, giving cinematographers the ability to work with shallower depth of field or in reduced lighting conditions.
At 100mm, this lens sits in telephoto focal length territory, making it an excellent choice for close-up work, portraiture-style framing, and selective compositions. Focus is entirely manual, requiring no motor or electronic autofocus system, which aligns with professional cinema production standards. The lens accepts front-mounted filters via its 95mm filter thread, and its classified anamorphic type signals the distinctive optical rendering this format delivers.
Weighing 3,084g, it is a substantial lens that demands appropriate support and rigging for stable operation on set.

Frequently Asked Questions — ARRI 100mm T1.9
What camera mount does this lens use?+
The ARRI Master Anamorphic 100mm T1.9 uses a PL Mount, which is the standard mount for professional cinema cameras. It is not compatible with DSLR or mirrorless camera mounts without a dedicated adapter.
What sensor format does this lens cover?+
This lens is specified for Super 35 format coverage, which is one of the most common sensor sizes in digital cinema production. It is optimized for cameras with Super 35-sized sensors.
Does this lens have autofocus?+
No. The lens is manual focus only, with no autofocus system. This is consistent with professional cinema lens design, where focus is typically controlled by a dedicated focus puller using a follow focus system.
What does T1.9 mean, and how does it differ from an f-stop rating?+
T1.9 is a T-stop rating, which measures the actual light transmission through the lens rather than the theoretical aperture opening. This makes T-stops more accurate for exposure consistency across different lenses on a cinema production, unlike f-stops which are calculated values.
What filter size does this lens accept?+
The lens has a 95mm filter thread, allowing for the use of standard screw-in filters at that diameter.
How heavy is this lens?+
The lens weighs 3,084g, making it a substantial cinema prime. Proper lens support and rigging are recommended when using it on a cinema rig.
