Sigma MOUNT CONVERTER MC-11 SA-E Firmware 1.28
Firmware 1.28 for MC-11 SA-E, fixing release lag during flash photography.
The Sigma 24mm f/3.5 DG DN Contemporary Sony E Firmware 04 updates Sigma’s compact Sony E wide-angle lens to correct an isolated issue reported with the Sony α7 V. Sigma says that, when this lens is used with that camera, the monitor could black out and the camera could freeze during shooting. For a small 24mm lens with an f/3.5 aperture, made for travel, street work, light landscape kits, interiors and discreet video, a stability correction can matter more than a flashier feature addition.
The value of this version sits in the electronic conversation between lens and body. The 24mm DG DN is the kind of compact optic many photographers leave in the bag for everyday use, and a camera lock-up can spoil a fast scene even if the fault only appears under specific conditions. Firmware 04 is meant to make the 24mm f/3.5 DG DN behave more reliably with the Sony α7 V while autofocus, monitor display, aperture control and mount communication are all active during capture.
Installation is handled through Sigma’s firmware page for Sony E by downloading the matching Windows or macOS updater. The lens must be attached to a compatible camera, with a fully charged battery or AC adapter in use; Sigma’s procedure also calls for removing the memory card where required, setting USB connection to Mass Storage, connecting the camera to the computer, and running Lens System Software Updater. Do not turn off or disconnect the setup during transfer; after completion, restart and confirm that the lens shows Ver.04.
