Black Magic Design Pty Ltd has shipped URSA Mini 4.6K cameras that appear to have an UNEVEN magenta cast issue. Whilst uniform casts may be easily fixable in post, uneven casts pose a much more significant challenge. More to the point, an uneven cast, which is readily demonstrable in large numbers of UM46 cameras, would appear to indicate a hardware issue has been missed or overlooked in the camera production process. It is unclear how many cameras may be affected. To date, the company has released no public statement regarding this issue, in spite of mounting numbers of concerned customers. Clearly, the company owes its customers the courtesy of a public statement which addresses the issue in detail.
