Sigma Firmware Update Adds Custom Dial and T-Stop Display to Eight L-Mount Lenses
Sigma has released a firmware update for eight L-mount lenses, enabling the manual focus ring to be remapped as a custom dial when autofocus is engaged. Users can assign functions like aperture, shutter speed, ISO, white balance, and more. The update also allows reversing the manual focus ring direction and displaying T-stop values during video recording. The update is free and available now via Sigma's website or the USB Dock UD-11. Supported cameras include recent Panasonic Lumix models, but notably not the Sigma BF. The lenses receiving the update are: 20mm f/2 DG DN | Contemporary, 20mm f/2 DG | Contemporary, 24mm f/1.4 DG DN | Art, 24mm f/2 DG DN | Contemporary, 24mm f/2 DG | Contemporary, 35mm f/1.4 DG DN | Art, 50mm f/1.2 DG DN | Art, and 500mm f/5.6 DG DN OS | Sports. Sigma has not specified whether older or future lenses will receive similar updates.
