Sigma · Released Oct 27, 2016 · First seen by GearPulse Jul 5, 2026
What's in this update
It is fully functional with SIGMA 12-24mm F4 DG HSM | Art, SIGMA 500mm F4 DG OS HSM | Sports and SIGMA 85mm F1.4 DG HSM | Art lenses.It has reduced the startup time between turning on the camera and taking an image by not initially driving the focus when the camera is turned on.When lenses with Optical Stabilizer (OS) function that are not fully compatible with SIGMA MOUNT CONVERTER MC-11 are attached with SIGMA MOUNT CONVERTER MC-11 and mounted on a camera which incorporates a stabilizer unit, it enables the camera’s stabilizer unit to be turned off and the lens’s OS function to be turned on and off.It has corrected the phenomenon where the distortion correction figure is not indicated properly in the camera, when SIGMA 24-105mm F4 DG OS HSM | Art is attached.
