Really its seems a match made in heaven. Vistavision-sized 4K sensor, + the production body of the URSA.
The 4K FF sensor of sony is capable of 60p scan, its S35 mode is capable of 120p. Is it possible to record a full QHD 60p form the FF sensor and 120p 1080 off the S35 mode? That would be awesome. Thsi sicurrently the most sensitive best dynamic ranged sensor on the market, it would be great if the URSA can unleash it.
