Large format, small camera

Fast and flexible

Embraced by the world’s leading filmmakers as soon as it was announced, the ALEXA Mini LF is ARRI’s flagship large-format camera. Versatile and adaptable due to its compact size, low weight, and multiple recording formats, the Mini LF offers the best overall image quality for large format and an exciting new REVEAL Color Science post workflow.

The best for large format

Distinct and cinematic large-format aesthetic
Creative and practical advantages over smaller formats
Highest dynamic range of any large-format camera

The ALEXA Mini LF was an ideal choice, capturing every detail authentically and allowing us to convey the intensity of the characters and the importance of the setting in a unique way. It is exceptional for close-ups, always keeping the essence of the surrounding environment alive.

I chose ALEXA Mini LF for my project because it offered me more flexibility. The shallow depth of field provided by the large format was essential, since I had very little distance between the LED wall and the talent.


Dario Scommegna


The large format was perfect for our film, because of the slightly enhanced way of separating the characters from the background.

The ALEXA Mini LF is a great handheld camera. I needed a camera with comfortable ergonomics that allowed me freedom to move around in space for long improvisations, and at the same time a good dynamic range and accurate color capture.


Wilssa Esser


The dynamic range and accurate color reproduction of the ALEXA Mini LF allowed me to create a dedicated look. This was a perfect opportunity to combine all my knowledge and experience with ARRI color science on the Mini LF.

First choice on big sets 

The gold standard of large format for countless top filmmakers
Proven sensor technology, trusted by the best in the business
Used on many award-winning productions

I love the sensor, the color sensitivity…I love the format because you can shoot a close-up with a slightly longer lens; I didn’t want that distortion you get with a wider lens.


Sir Roger Deakins CBE, ASC, BSC


The ALEXA Mini LF has made possible what I thought was previously impossible with large-format photography. The freedom it allows me as a DP, to move the camera in whatever way I feel is best, is unbeatable.


Greig Fraser ACS, ASC


When filming in a volume, you want to avoid having the LED screens in focus, which led us to the ALEXA Mini LF. The camera gave me the immersive large-format look that I really like and could be fed with a genlock signal to communicate directly with the LED wall.

Safe investment  

Taking owner-operator careers to the next level
Production companies can target high-caliber clients
ARRI cameras hold their value better than any others

Owning an ALEXA Mini LF has really helped us grow as a company, elevating us to be able to produce three indie features in three years, and to move from a small basement to three offices with eight full-time employees.

Owning a Mini LF has opened up a whole new dimension of cinematography for me. The unique field of view and the ability to isolate talent within a frame has given my work a distinctive look. Being an owner-operator means I can use it on a variety of projects, no matter the budget. 


Chris Bell


The wildness of some of the locations was one of the reasons why I chose the ALEXA Mini LF, because I knew I could trust it.


Josua Stäbler about shooting with the ALEXA Mini LF for the YouTube climate change series, “Seat at the Table”


Multiple recording formats 

The ALEXA Mini LF offers a wide choice of recording formats, among them 4.5K Open Gate and anamorphic Super 35 that fulfills 4K mandates. Multiple frame lines can be used simultaneously, including a vertical 9:16 crop for social media that takes full advantage of the tall ARRI sensor. Ideal for multi-format shoots or whatever aspect ratio, resolution, and data rate suit your production, the Mini LF is truly cinematic, and truly flexible. 

The perfect tool for virtual production

Real-time camera and lens metadata is supported through ARRI’s UMC-4 and the ARRI Live Link Metadata Plug-in for Unreal Engine, while native genlock support delivers accurate sync. The large sensor limits depth of field and helps avoid moiré artifacts.

40% savings of time and budget with HDE

CODEX High Density Encoding (HDE) is a loss-less encoding scheme that reduces ARRIRAW file sizes by around 40%. Despite the smaller footprint, HDE does not compromise on quality. Once decoded, the output results in a bit-for-bit perfect match to the original ARRIRAW file. Supported by leading content providers and postproduction applications, HDE reduces storage, shortens transfer times, and speeds up workflows, which translates to direct savings of time and money.

Full suite of professional accessories 

The many accessory options for the ALEXA Mini LF further enhance its flexibility and make it suitable for a huge range of shooting styles. Our three Ready to Shoot Sets include everything you need except a card reader, as there are two to choose from. Lightweight, modular, and based on decades of experience, ARRI accessories are famously rugged and reliable. SAM plates provide a quick way to transition from shoulder or tripod to stabilizer. 

Tech Talks


  • The ALEXA Mini LF uses the same sensor as the ALEXA LF. This is the ALEV 3 A2X sensor, which has the same photosite size and type as ARRI Super 35 digital cameras. The ALEV 3 A2X has 4448 x 3096 photosites (yes, it is therefore a 4.5K sensor) and measures 36.70 x 25.54 mm / 1.444 x 1.005" and requires a 44.71 mm / 1.760" image circle.

  • The ALEXA Mini LF supports large-format as well as Super 35 recording formats, please see the table below. 

  • The ALEXA Mini LF (left) has the same dimensions and the same mounting points as the ALEXA Mini (right), except for the media bay on the camera left side. The ALEXA Mini LF camera body with an LPL lens mount weighs 2.6 Kg/5.7 lbs. The ALEXA Mini LF MVF-2 viewfinder weighs 800 g/1.7 lbs.

  • The ALEXA  Mini LF uses the new, small and cost-effective Codex Compact Drive 1 TB and 2 TB. 
    The Compact Drive has been specifically designed for the small form factor of our cameras, using new flash technology in a miniaturized tough enclosure. The ALEXA  Mini LF accepts Compact Drives directly, without the need for an adapter. ALEXA  LF and ALEXA SXT  W do not support the Compact Drive. 
    Both ARRIRAW and Apple ProRes recording can utilize the drive's full recording capacity. The drive will be formatted by the ALEXA  Mini LF in the UDF format for ARRIRAW and Apple ProRes. Therefore, both ARRIRAW and Apple ProRes can be recorded onto the same media without reformatting or switching drives.
    To get an overview of recording media for ARRI cameras, please take a look at the Supported Recording Media document.

  • The ALEXA Mini LF has an input voltage range from 11 V to 34 V. Therefore, it can be easily powered by any 12 V on-board battery as well as by a 24 V on-board battery. The ALEXA Mini LF has a power draw slightly higher than the ALEXA Mini, at around 65 W when recording ARRIRAW at 24 fps with the MVF-2 viewfinder connected. Electronic accessories will, of course, increase power draw.
