Lens Overview — ARRI 75mm T1.8

The ARRI Signature Prime 75mm T1.8 is a manual-focus cinema lens built for the PL Mount and designed around full-frame coverage. With a maximum aperture of T1.8, it sits firmly in the fast-prime category, offering cinematographers the ability to shoot in lower light conditions and achieve a shallow depth of field when the creative brief calls for it. As a prime lens with a focal length of 75mm, it occupies a classic portrait-friendly position in the standard range — useful for close-up character work, dialogue scenes, and detail shots.

The lens is manual focus only, which is standard practice in professional cinema workflows where a dedicated focus puller operates the lens independently of the camera operator. Weighing in at 1.9kg, it carries a substantial but workable heft typical of high-end cinema glass. The PL Mount is the industry-standard cinema mount found on professional cinema cameras, making this lens compatible with a wide range of professional cinema rigs.

There is no image stabilization, which again is entirely expected for a lens of this class, as cinema productions rely on rigged support systems rather than optical stabilization. This is a full-frame lens built squarely for the Cinema and Video camera system category.

Description — ARRI 75mm T1.8

The ARRI Signature Prime 75mm T1.8 is a professional cinema lens built on the PL Mount and designed to cover full-frame sensors. With a maximum aperture of T1.8, it gives cinematographers meaningful low-light capability and the ability to draw a subject away from the background with a shallow depth of field. The 75mm focal length sits in the standard range, making it a practical choice for portrait-oriented work, dialogue coverage, and detail shots where a slightly compressed perspective is useful.

Focus is entirely manual, which is the standard for professional cinema glass — operated by a focus puller using a follow focus or wireless lens control system. The lens weighs 1.9kg, placing it in the substantial but field-practical range for a fast full-frame prime. There is no image stabilization, consistent with professional cinema practice where support rigs handle camera movement.

The lens is categorized as a prime with a cine type designation, purpose-built for the Cinema and Video camera system category.

Frequently Asked Questions — ARRI 75mm T1.8

What camera mount does the ARRI Signature Prime 75mm T1.8 use?+
The lens uses a PL Mount, which is the standard mount found on professional cinema cameras. This makes it a natural fit for high-end cinema production environments. Adapters may allow use on other systems, but the lens is designed for PL Mount cameras.
Does this lens support autofocus?+
No, the ARRI Signature Prime 75mm T1.8 is a manual-focus-only lens. This is standard for professional cinema lenses, where focus is typically controlled by a dedicated focus puller using a follow focus system.
What sensor formats does the 75mm Signature Prime cover?+
The lens is rated for full-frame coverage, meaning it can cover full-frame and compatible large-format cinema sensors without vignetting. It is categorized under the Cinema and Video camera system.
How heavy is the ARRI Signature Prime 75mm T1.8?+
The lens weighs 1.9kg. While manageable, this weight is worth factoring into decisions around gimbal payload capacity, handheld rigging, and lens support systems on set.
Does the lens have image stabilization?+
No, image stabilization is listed as None. Cinema productions using this lens would rely on external support systems such as gimbals, fluid heads, or camera rigs to achieve stabilized footage.
What is the aperture of this lens and what does T1.8 mean?+
The maximum aperture is T1.8, expressed as a T-stop rather than an f-stop. T-stops are a cinema-standard measurement that accounts for light transmission through the lens, making exposure consistency more reliable when cutting between different lenses in a set.
