The Ursa 4K and Ursa Mini 4K both have a global shutter, but have slightly less DR and it’s base ISO is 400, compared to the 4.6 sensor which is 800. The 4.6 also has a Rolling Shutter. They are both very good cameras, each has its advantages and disadvantages. It all depends on what you are shooting and the look you want.
The big Ursa 4K is more of a production camera aimed at studio work, and the 4.6 more of a cinematography camera. Also the Ursa 4K was designed for a two/three person crew to run, in addition to a single operator camera. The Mini’s are primarily a single operator camera, or one Cameraperson and one focus puller.
The big Ursa also has better cooling and can produce a somewhat cleaner image than the smaller Ursa 4K, with its better cooling. Feature wise, the Minis enjoy a newer operating system and improved menu setup.
The main selling point in the big Ursa was it could have a new sensor/turret upgrade, but this has never materialized.
Given the great deals available on the big Ursa, it is a very good buy, if the camera will suit your needs.
We got one for Studio chroma key work, which looks great. A disadvantage for use however,mismthr big Ursa is progressive only, and unlike the Minis, it can not output an interlaced (1080i) PsF signal.
