Sigma Mount Converter MC-31 Will Cost $679, Ships February 27

The wait is now over for the availability of the Sigma Mount Converter MC-31, the development of which was announced in September 2019.

If you’ve been eagerly waiting for availability and shipping updates on the Sigma Mount Converter MC-31, the wait is now over. The company has finally announced today that shipping will begin on February 27th, and will retail for $679 from authorized Sigma dealers.

For those who are just learning about this new offering, the Sigma Mount Converter MC-31, whose development was announced in September 2019, allows PL-mount lenses to be used with L-Mount cameras such as the Sigma fp, and those from Leica and Panasonic. This is especially significant for photographers who also dabble in filmmaking using PL-mount cine lenses.

Sigma Mount Converter MC-31 Key Features:

Shim Adjustments

The MC-31 has shim adjustments on two points of the mount. The flange depth can be adjusted on the camera-side mount as well as the lens-side for proper calibration of both camera and lens accuracy.

All-Metal Construction

With an aluminum-alloy body and strong brass mount and locking ring, the MC-31 boasts excellent durability. It is also designed to be fastened on the mount of the Sigma fp with a screw thread, ensuring an even more secure connection between the lens and the camera. This allows users to shoot steady without the lens rattling even after long-term use.

Tripod Socket

The removable tripod socket allows MC-31 to be attached to a tripod or other filmmaking accessories such as a camera cage.

Secure Lens Mounting

With the screw thread removed, the stopper of the locking ring is released. This makes it possible to use MC-31 with a PL mount lens that requires tighter mounting than the MC-31’s specifications, allowing the lens to lock securely in place on the converter.

Luminous Paint for Low Lighting  

The markings on the upper part of the converter are in the same luminous paint as the one used for Sigma Cine Lenses, helping make it easier to replace or adjust a lens in the dark.
