MC-31 has shim adjustments on two points of the mount. Adjustments can be made with a shim kit (Supplied) on the camera side of the mount2,or a shim for ARRI digital cameras on the lens side1.
All-metal construction for excellent durability
With an aluminum-alloy body4and strong brass mount and locking ring5,MC-31 boasts excellent durability.
It is also designed to be secured on the mount of the SIGMA fp with a screw thread3,ensuring an even more secure connection between the lens and the camera. This allows users to shoot steady without the lens rattling even after the long-term use.
The removable support foot6allows MC-31 to be attached to a tripod or other filmmaking accessories such as a camera cage.
Suitable for various shooting conditions
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.
The markings on the upper part of the converter are in the same luminous paint as the one used for SIGMA CINE LENS, helping make it easier to replace or adjust a lens in the dark.
