Sigma has released a series of updates for several targets but also a note indicating an incompatibility with two of his software. Starting from the latter, the company announces that Photo Pro 6.7.4 and the X3F plug-in for Photoshop do not work correctly on macOS 11.0.1 Big Sur.
The manufacturer is aware of the problem and is working to fix it as soon as possible. Currently there are two solutions: either not to upgrade to macOS Big Sur or do not use the two software involved until the update is ready.
Firmware updates for Sigma lenses
As written above, the firmware of a series of targets with different attacks. Here is the list of models involved with the various news. Users, as always, are encouraged to update in order to have access to the latest features and bug fixes that may be present in older versions.
Canon EF lenses
The first model is the 12-24mm F4 DG HSM Art which with the new update has an optimized exposure when viewing from the viewfinder with the EOS 90D and EOS-1D X Mark III. Also solved the communication problem during Live View shooting with EOS-1D X Mark III.
The 24-35 mm F2 DG HSM Artcorrected the same problems as the previous model with the new firmware, and reduced the operating noise of the aperture blades when used with the MC-11 EF-E when shooting movies. Also reduced noise when used with Canon cameras in general.
The 24 mm F1.4 DG HSM Art, with the new firmware released by Sigma, no longer has the problems encountered as for the previous model, with the exception of the note relating to Live View.
The 50-100 mm F1.8 DC HSM Art has improved exposure with the Canon EOS 90D. As for the 60-600mm F4.5-6.3 DG OS HSM Sport and the 35 mm F1.4 DG HSM Art you have an optimized exposure for the EOS 90D and EOS-1D X Mark III.
Sony E and L-Mount lenses
Two objectives have also been updated with other attacks. The 16 mm F1.4 DC DN Contemporary with Sony E mount with the new firmware can be used to best effect when focusing. Instead the 35mm F1.2 DG DN Art for L-Mount is now compatible with the focus ring adjustment functionality. In addition, the quality of aperture operation and AF tracking during movies has been improved, and AF performance with a distant subject has been improved.
