Project Description

ALEXA 35 is a 4K Super 35 camera that elevates digital cinematography to unprecedented heights. ARRI’s first new sensorfor 12 years builds on the evolution of the ALEXA family over that period, delivering 2.5 stops more dynamic range, film-like highlight handling, better low light performance, and richer colours.

The new REVEAL Colour Science takes full advantage of the sensor’s image quality and provides a fast, simple workflow, while ARRI Textures enhance in-camera creative control. Easy operation, robust build quality, new electronic accessories, and acomplete new mechanical support system round out the ALEXA 35 platform.

More dynamic range with filmic highlight roll-off

ALEXA 35 measures at 17 stops of dynamic range (exposure latitude), far more than any other digital cinema camera. Filmmakers gain 1.5 stops in the highlights and a stop in the shadows over previous ALEXA cameras, while retaining the naturalistic, film-like highlight roll-off. Sophisticated stray-light suppression ensures that the full character and contrast range of each lens is captured. Together, the increased dynamic range and stray light control make it easier to handle any lighting conditions on set, increase flexibility in post, and provide the best possible source for HDR (High Dynamic Range) projects.

More sensitivity up to EI 6400, with lower noise

Impressively low noise and sensitivity settings ranging from EI 160 to EI 6400 make ALEXA 35 a “High ISO” camera. An optional Enhanced Sensitivity Mode can be applied to settings between EI 2560 and EI 6400, producing aneven cleaner image in low light. This exceptional sensitivity, combined with the wider dynamic range and truer contrast, allows ALEXA 35 to capture the most delicate nuances of light and shadow in a wider range of shooting situations. Filmmakers can work with available light in real locations, safe in the knowledge that even at extreme ISO values, any noise will have a pleasingly film-like structure.

More accurate colours from bold hues to subtle tones

Introduced alongside the ALEXA 35 is REVEAL Colour Science, which is the collective name for a suite of image processing steps that, along with the new sensor, help the camera to record more accurate colours with subtler tonal variations. Skin tones of all types and colours are rendered in a flattering, lifelike way. Highly saturated colours such as those in neon signs or car brake lights are captured with incredible realism, as are typically challenging colours like cyan, burgundy, and pastel shades. Overall, the true-to-life colour fidelity and amazing resolving power of the sensor make for beautiful, immersive images.

More creative control. ARRI Textures – choose your digital film stock

ARRI Textures provide a new and unique way for cinematographers to exert greater creative control on set.A texture defines the amount and character of grain in an image, as well as the amount of contrast at different levels of detail, perceived by the viewer as sharpness. Previous ALEXA cameras were pre-programmed with a default texture, but with ALEXA 35 you can choose from an evolving menu of custom ARRI Textures, either to suit a specific shooting environment or to hone your look. This allows you to fundamentally alter the way the camera records images, much like selecting a film stock

Super 35 sensor wide lens choice, 19 recording formats

With its Super 35 4:3 native 4K sensor, ALEXA 35 can be used with the vast global inventory of existing lenses—modern and vintage, anamorphic and spherical, Super 35 and large format. Filmmakers wanting to shoot with ARRI cameras while having to fulfill 4K mandates now have an immeasurably broader lens choice.
A total of 19 recording formats, incorporating efficient in-camera downsampling and anamorphic de-squeezing, allow productions to optimize data rate, resolution, and other parameters, based on their individual needs. Mixed Reality Productions (MRP) will benefit from the camera’s ability to record lens metadata in all common standards and output real-timestreaming metadata to ARRI’s Live Link Metadata Plug-in for Unreal Engine.

Faster workflow, higher image quality

ARRI’s discussions with filmmakers and careful review of the image pipeline have led to significant image quality enhancements and a faster,easier workflow. REVEAL Colour Science is a suite of new image processing steps used by ALEXA 35 internally and also available through leading third-party postproduction tools for ARRIRAW processing. It includes an improved debayering algorithm for cleaner compositing, a new colour engine for more accurate colour reproduction, a new wide gamut native colour space for faster grading, new LogC4 encoding to contain the increased dynamic range, and new LogC4 LUTs (Look Up Tables) for enriched colour fidelity.

Fast and easy to use. A single, rugged camera that can do it all

ALEXA 35 is the smallest fully featured ARRI production camera ever, packing the features and processing power of a larger ALEXA intoa Mini-sized body. Crews will be intuitively familiar with the simple menu structure; support for 1TB and 2TB Codex Compact Drives; andMVF-2 viewfinder, now with HDR. Fast and easy operation is assured through usability improvements such as a new left-side display and additional user buttons. Temperature resistant, splash and dust-proof, and conceived with future hardware and software updates in mind, ALEXA 35 is the best A-camera, B-camera, and drone or gimbal camera on the market, all rolled into one.

Support for any situation. Electronic accessories and mechanical support

ARRI has crafted a new line of bespoke ALEXA 35 accessories that expand the camera’s capabilities and ensure maximum speed andversatility on set. Closely integrated electronic accessories offer additional power outputs or extended audio features. A complete new setof mechanical support items provides flexible options for any situation, scaling quickly and easily from a small and lightweight setup to a full-blown production configuration. ALEXA 35 is available in sales sets that group together components suitable for different shootingstyles and production types, with further accessories and system options facilitating countless setups.

Powering the future. B-Mount, the new 24 V standard

ALEXA 35 utilizes the B-Mount battery interface, an open industry standard endorsed by ARRI and thewider industry. Providing high-capacity 24 V power, but also able to support 12 V, B-Mount offers more efficiency and improved data communication over previous systems. Cross-compatible with camera, lighting, and stabilizer equipment from manufacturers worldwide, it enables productions to streamline their power requirements.
