Exceptionally soft bokeh for increased sense of separation – like looking through a window in the rain.

They produce optimal results with all sensors due to their near-telecentric design.

These are multi-award winning lenses.

The timeless look of Arri Signature primes with never go out of style.

LPL Mount

The new LPL (Large Positive Locking) mount is an open-standard, camera independent mount which covers all image circles up to large format 46mm.

The mount has backwards compatibility with PL Mount through the rock solid PL-LPL adaptor.

The Arri Signature Primes are the perfect accompaniment to our Arri Alexa Mini LFs.

Next Generation LDS-2 Lens Data System

Arri Signature primes are the first lenses to incorporate Arri’s next generation LDS-2 lens data system, with high data rates and absolute encoders for fast initialising.

Detachable Magnetic Rear Filter Holder

Any material can be used to make a filter, from tinfoil and fishing line to stockings, wrapping paper, and vintage fabrics—each of them affecting bokeh, flaring and diffusion in different ways. Alternatively, glass elements can be used to simulate vintage lenses, with images sharp in the centre but deteriorating in the corners. Simply visit your local optician with a filter holder and ask them to fit a close-up lens of whatever strength, coating or tint you want to try. The filter holder is magnetic, allowing fast and easy changes between looks, with no tools needed.

An additional way to explore different looks with the Signature Primes is to use ARRI’s uncoated replacement front element, which can be fitted by the user in just a few minutes to increase flaring, ghosting and reflections.

Discover how retro filmmaking techniques such as nets, and diopters can help you customise the look of the Signature Prime lenses.


LPL compatibility


Arri Signature Primes are equipped with the LPL (Large Positive Locking) lens mount. A wider diameter and shorter flange focal depth allow LPL lenses to be small and lightweight, with a fast T-stop and pleasing bokeh—a combination of features that would not be possible with the old PL lens mount.

ARRI has shared LPL specifications openly and free-of-charge across the industry, establishing the LPL lens mount as a standard interface between cameras and lenses. ARRI LPL lens mounts are available for ALEXA 65, ALEXA LF, ALEXA Mini LF, ALEXA Classic/XT/SXT, ALEXA Mini and AMIRA cameras. In addition, third parties offer LPL lens mounts for cameras, director’s viewfinders, and lens testing tools, so Arri Signatures and other LPL lenses can be universally used.
