Science of the Beautiful

CION™ is the new 4K/UltraHD and 2K/HD production camera from AJA. Shoot direct to edit-ready Apple ProRes 4444 at up to 4K 30fps, ProRes 422 at up to 4K 60fps, or output AJA Raw at up to 4K 120fps. CION is the union of great design and functionality, an engineered aesthetic that we are proud to describe as the Science of the Beautiful.

Shoot What You See

CION can encode 4K/UltraHD and 2K/HD directly to 12-bit ProRes 444 internally. Using this high quality and widely supported codec to record CION’s film-like image and superb color rendition will provide the easiest route to post production for 4K yet. CION’s extensive Gamma modes offer great flexibility to let you capture the scene exactly as lit in Normal, Normal Expanded or Video Gamma modes. Expanded 1 and Disabled allow more latitude in post for you to create your own look and feel.

CION Gamma Modes

Expanded 1

This gamma mode allows the widest possible dynamic range when shooting. The frame shown is taken from an UltraHD ProRes 444 sequence; The image itself was exposed to get as much detail as possible in the sky part of the frame. The before version is lower in contrast and seemingly lacking in smooth gradients and fine detail. However, the after version clearly shows just how much picture information is available in post. Note the subtle gradients of the sky and the detail that emerges within the shadowed sections of the image.


This gamma mode effectively disables any adjustment curve being made to the image whatsoever. The frame shown is taken from an UltraHD 422 sequence; Exposure in this image was controlled to expose the highlights behind the actor. The before version appears very dark with little definition to the actors face. The after version again shows just how much information can be lifted within the picture, effectively allowing the visual drama of the scene to be closely controlled in post by lifting the shadows accordingly.

Normal Expanded

This gamma mode allows slightly more range than the Normal gamma selection. The frame shown is taken from an UltraHD 422 slow motion sequence; the before version is darker and was exposed to capture the window highlights from the sun rise. The after version shows that the latitude available to lift the image and create defined highlights and mid-tones is considerable.

ProRes® Workflow

The ProRes 444 and 422 workflow for CION allows you to capture high quality images in an easily managed file format and size. The Pak dock provides fast transfer of footage into your local media storage and directly into a wide range of NLEs and finishing tools of choice with no need for transcoding. Native file recording means you’re able to better connect production to post; keeping the image quality at it’s highest throughout.

AJA Raw External
Recorder Support

As well as high quality Apple ProRes acquisition, CION now offers portable capture of AJA Raw, up to 4K 60fps by third party external recorders. Integration of these devices is very easy given CION’s open design and intuitive menu structure. AJA Raw offers the highest quality experience in post production in almost any of the leading editing or finishing tools available.

30fps AJA Raw Workflow

CION offers easy output of up to 4K 30fps AJA Raw via the Thunderbolt™ connector on the rear of the camera and by using AJA CamXchange and a Thunderbolt enabled fast RAID and laptop. Perfect for studio environments where complex, keyed shots require the most post production processing.

60fps AJA Raw Workflow

Although CION offers full 4K ProRes 4444 encoding at 12-bit internally to Pak media you may also elect to output AJA Raw to other best-in-class products from AJA with our proprietary, powerful but totally free AJA Control Room software and connected fast RAID storage. Use AJA Io® 4K to capture AJA Raw over SDI at up to 60fps at 4K to provide outstanding post production quality for even the most demanding grade or visual FX requirements.


120fps AJA Raw Workflow

You can also choose the unrivaled AJA KONA® 4 to capture up to 120fps at 4K via the 4 x 3G-SDI outputs to create beautiful and detailed slow motion with an engaging cinematic feel via AJA Control Room.

Science of the Beautiful

AJA’s approach to the development of CION was not only towards the external aesthetic and it’s deliberate ergonomic styling; the image processing itself was considered throughout with the result being outstanding color accuracy in virtually any environment. CION is capable of capturing images at up to 4K 12bit 444 allowing the broadest dynamic range possible and providing excellent latitude for post production finishing. To minimize the amount of post processing required CION also allows for great flexibility in controlling the image captured by using our intuitive menu system and it’s straightforward operation on-set. A variety of gamma curves are found within the Exposure Index menu to suit the highlights and shadows within a given scene. In addition you can choose from a range of color temperatures within the White Balance menu providing standard values to suit your scene. You are also able to Auto White Balance any scene by simply holding down the ‘WB’ button on the operational side of CION for three seconds. For those situations where more precise color control is beneficial on-set you can control both the Saturation and also Color Correction via their corresponding menu options. This additional control can save valuable time in post, especially on tight deadline projects which require speedy delivery to broadcast and allows you to adapt to changing light in even the most demanding environments.

PL Lens Mount

PL mount lenses are the industry standard for cinema and professional production cameras, and are widely available the world-over. In addition, CION’s lens mount has been designed to be removable so third parties may develop mounts for other lens types.

Optical Low Pass Filter and
IR Cut Filter

An integrated OLPF (Optical Low-Pass Filter) reduces unwanted moiré effects while still retaining vital image detail.

The Infra-red cut filter produces high quality colors within the image by
blocking unwanted light wavelengths.


CION features a 4K APS-C sized CMOS sensor with an electronic global shutter and 12 stops of dynamic range. Lenses designed for Super 35mm cover the sensor imaging area and the global shutter eliminates the undesirable qualities associated with rolling shutter-based sensors.

Recording formats

CION can record at 4K (4096x2160), UltraHD (3840x2160), 2K (2048x1080) and HD (1920x1080). 2K and HD are hardware scaled from the full 4K sensor, resulting in beautiful over-sampled images, which also retain your lens’ focal length at any desired resolution. Frame rates up to 50 and 60p are supported - even at full 4K resolution.

AJA Pak Media

CION uses AJA’s proven SSD-based Pak storage. The robust high speed compact storage mounts directly in-camera and allows recording of 4K/UHD and 2K/HD as ProRes 4444, ProRes 422 (HQ), ProRes 422, ProRes 422 (LT) and ProRes (Proxy). Choose from generous 256GB or 512GB capacities and by utilizing the AJA Pak Dock (sold separately) you can transfer your footage over high-speed Thunderbolt™or USB3.

More Info


Aluminum cheese plates are fitted to both the top and the bottom of the chassis to provide easy mounting of accessories from both AJA and third parties, with standard thread sizes to offer the widest range of compatibility.

Conveniently Connected

CION’s considered design brings ease of operation to both field and studio based productions. For single users, set up and operation is intuitive. For complex productions that require camera operators, camera assistants and digital imaging technicians CION offers unrivalled flexibility. In such a scenario, the camera operator can use one monitor output for framing, the camera assistant another monitor output for judging focus and the digital imaging technician can use yet another monitor output as well as the web UI to configure the unit with total resolution independence. CION offers more simultaneous monitoring outputs than any other camera.

Up to twenty banks of presets can be saved bringing huge flexibility and time saving whilst shooting.

Elegant Operations

All interface controls are found on the side of the camera facing the operator to provide easy single user functionality. The menu structure itself is elegant and free of cumbersome sub-menu navigation. Confidently dial settings with a robust selection knob that gives clear mechanical feedback as you adjust.

The integrated confidence monitor not only displays the menu information but also previews your real-time image, allowing independent operation.

LED VU meters are placed for easy and accurate audio monitoring. Control knobs for each audio channel allow adjustment of the input level. A headphone monitoring output and a headphone volume control knob are also provided.


On-Set backup and monitoring workflow

CION provides unrivalled on-set monitoring options for 4K/UHD and 2K/HD including a hardware dedicated down convert for 4K/UHD to 2K/HD. CION’s outputs are simultaneously live allowing great flexibility in any scenario independent of resolution. When working in 4K or UHD, five outputs are always available with two for 4K via the HDMI and 4 x 3G SDI and as well as three dedicated downconversions via 2 x 3G SDI and 1 x HDMI. If you are working
in HD or 2K then every single output is live at that resolution giving you up to eight outputs to share on-set. The built in confidence monitor also allows yet another way to see the image being captured.

The AJA Pak Dock and Pak media are designed for field use, featuring a rugged and reliable form factor; unlike a bare SSD drive, AJA Pak media features a multi-insertion rated connector. Connecting to CION via the LAN connector provides real time information regarding the Pak currently in use and by utilizing a Thunderbolt enabled RAID storage drive you can quickly back up your Pak media as you shoot.
