History
At the NAB Show in April 2014, Blackmagic Design announced the URSA digital movie camera, which was the first movie camera to be user-upgradeable for additional equipment, alongside the Studio Camera, the television-oriented version of the Cinema Camera. In November, a firmware update maxed the frame rate to 80p and added a new 3:1 compression ratio for RAW files.
In April 2015, the URSA Mini was announced and all URSA models and variants received another update that upgraded the maximum frame rate for the windowed 1080p resolution to 150 fps and added support for Apple ProRes 444 XQ and updated the models with a second-generation sensor. A B4 lens mount was added to the Mini in September. The 4.6K version of the Mini was then released in March 2016, controversially without global shutter. In August, a public beta of the redesigned Camera Utility 4.0 for URSA Mini was released.

Specifications and hardware
The camera can come in both 4K and 4.6K specifications, with max resolutions being 4608 x 2592 for the 4.6K spec and 4000 x 2160 for the 4K. All models and variants include DaVince Resolve. The camera comprises two displays; the main 10.1" flip-out TFT-LCD display that is controlled using physical buttons and a 5" LCD capacitive touchscreen that can show recording status and can be used to access features by another operator. The camera records lossless CinemaDNG RAW, RAW 3:1 and 4:1 and Apple ProRes.
Software
The URSA uses Camera Utility, the proprietary software developed by Blackmagic also in use for the Cinema Cameras. The software allows the user to add metadata about a single file, including - but not limited to: shot, take and scene numbers, as well as filenames. However, the system must be updated through a computer using USB instead of other technologies like firmware over the air.
Models and variants
The URSA is available in four different models: EF, PL, HDMI and Broadcast. The EF and PL mounts are interchangeable and can work with any compatible lenses. However, the HDMI model doesn't have a lens system at all and a separate camera must be connected to the camera via HDMI to record. It has a threaded camera mount to mount a camera onto the URSA. The Broadcast model uses an optimized sensor for broadcasting in Ultra HD, as well as a specialized B4 lens mount and a neutral-density filter wheel on the body.
URSA Mini
The Blackmagic URSA Mini is a variant of the URSA camera. The 4.6k variant was released on March 17, 2016. It has a smaller form factor and loses some functionality and features over the URSA, losing the secondary 5" touchscreen, global shutter on the 4.6k variant and other features. However, it does ship in 4K and 4.6K specifications, and ships in EF and PL mounts.
URSA Mini Pro
The Blackmagic URSA Mini Pro, the most recent variant of the URSA camera, was released on March 2, 2017. Compared to the URSA Mini, it adds an internal neutral density wheel, shoulder-accessible controls, and a secondary 4" touchscreen, and ships only in a 4.6K specification. Its most unique feature is a user-interchangeable lens mount. The camera ships with an EF mount, and at release time, PL and B4 mount modules were available for purchase.
URSA Broadcast
The Blackmagic URSA Broadcast, the most recent variant of the URSA camera, was released on February 1, 2018. While not an URSA "Mini", the Broadcast uses the same platform as the URSA Mini Pro. The camera features a 4K sensor, 2/3" style B4 lens mount, traditional external controls (like on the Mini Pro), built in optical ND filters, and dual CFast and dual SD card recorders. While the Broadcast ships with a B4 sensor, the camera is compatible with EF, PL and F mounts, sold separately by Blackmagic.
Accessories
Viewfinder
The Blackmagic URSA Viewfinder is a viewfinder made by Blackmagic Design. It comprises a 1080p OLED screen and can be focused and adjusted to both the left and right eye and only turns on by a proximity sensor dubbed the "Eye-sensor". The diopter is also user-adjustable. It screws onto the top of the URSA and URSA Mini or onto any mount compatible and connects via BNC-SDI connection and XLR, making it compatible with cameras that have these ports.
Studio Viewfinder
The Blackmagic URSA Studio Viewfinder is a viewfinder display made by Blackmagic that is exclusively for the URSA Mini. It comprises a 7" 1080p LCD screen, a menu button and three function buttons that can display various exposure, focus and framing guides and four knobs that bring up the menu and control the brightness, contrast and peaking sensitivity. It mounts on top of the Mini camera and is adjustable, has a removable sun hood and metal handles on the side.
