Sigma has announced that its MC-31 Mount Converter will go on sale at the end of this month, and will retail for a price of $679 / £649. The lens accessory allows you to fit any PL-mount cine lens onto an L-mount mirrorless camera.
The PL-mount is the standard bayonet fitting in the filmmaking industry – originally pioneered by Arri, but widely adopted by all cine lens manufacturers.
The L-mount is the full-frame mirrorless mount developed by Leica - but which is now also used on Panasonic and Sigma full-frame mirrorless cameras, such as the Sigma fp and the Panasonic S1R.
The Sigma Mount Converter MC-31 has an aluminum alloy body, a brass mount and the standard PL locking ring which ensures a secure connection between lens and camera.
The adaptor has in-buit shim adjustments, that allow the user to adjust the flange depth to be adjusted on two points on the mount – to ensure that the lens and camera sensor are perfectly aligned.
Weighing 330g, the MC-31 has a removable tripod socket, and the markings on the converter are in the same luminous paint found n Sigma's own cine lenses, to ease of operation in low light.
