Blackmagic Design is shipping its delayed Ursa Mini camera and its Micro Cinema Camera without the global shutter feature that was promised when the cameras were unveiled last year.

The company said that development of the shutter had taken longer than expected and that it wasn’t currently good enough to include. 

In a statement the company said: “For the past six months, Blackmagic Design engineers have been working extremely hard to resolve the issues.

“As the performance of the global shutter is not up to the high quality level that Blackmagic Design strives to give its customers, Blackmagic Design have decided to ship both of the cameras without the global shutter feature.”

Both cameras are being made available with rolling shutters instead. 

“We understand and accept that some customers who have back ordered an Ursa Mini 4.6K may like to change their order as a result of this feature change,” the company said.

The Ursa Mini 4.6k is one of four Mini models. The 4.6K version has a sensor that captures 4608 x 2592 pixels and offers up to 15 stops of dynamic range.

The Micro Cinema Camera is a remote-controlled Super 16mm-sized digital film camera.
