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?+

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.
