Blackmagic has experienced some growing pains with regards to its Ursa Mini 4.6K camera. First exhibited at NAB 2015, the camera took another year to see the light of day, sans the global shutter of its original spec sheet. However, even with a rolling shutter, our reviewer Ned Soltz positively reviewed the Ursa Mini 4.6K, citing "rich and organic" skin tones and its apparent wide dynamic range, concluding that it "can deliver excellent results for a relatively low investment."
Ned did mention the Ursa Mini 4.6K's "magenta tinge issue" that has been making the rounds online. He was not able to reproduce the unwanted effect, but the company has just released an update to its camera software which may address the issue.
Camera Setup 3.3, which affects the Ursa Mini 4.6K, 4K and Viewfinder, brings a handful of tweaks to each product. The most noteworthy may be an enhancement for the 4.6K, regarding "improved sensor response to lens shading," which could directly address the issue of magenta corners in certain shooting situations.
In addition, the new camera software gives the Ursa Mini 4.6K improved default white balance, while both cameras and the Viewfinder should exhibit improved saturation in VIDEO dynamic range mode.
