"This update was originally released and then suspended on August 24, 2022, because some products could not operate properly after the update to Ver.1.10. However, the update has resumed with countermeasures, and we are happy to bring all of its added functionality to the Alpha 7 IV."
Note: "This update is executed via SD card/CFExpress card, and users will need to ensure the Alpha 7 IV is running or updated to Ver.1.05 first, before updating to v1.1. Instructions can be found in the links in the release."

New Alpha 7 IV Firmware Update Enables Lossless RAW File Options and Improved Accuracy and Operability
SAN DIEGO, CA – August 23, 2022 – Sony Electronics Inc. today announced the v1.1 firmware update for the Alpha 7 IV full-frame mirrorless interchangeable lens camera, adding Lossless Compressed RAW in three sizes for still images, shutter speed and ISO setting retention, touch shutter function, improved Eye AF (autofocus) accuracy and more. ? ?
The update adds Lossless Compressed RAW files in S, M and L (small, medium or large) file sizes – a highly requested feature. Selecting L size preserves the same image quality as an uncompressed RAW format while significantly reducing the file size. The M and S sizes record fewer pixels than the L size, providing even smaller RAW file sizes.
Alpha 7 IV v1.1 allows photographers to retain shutter speed and ISO settings for flash photography. This newest update also offers a Touch Shutter Function and improves the accuracy of the Eye AF feature.
Other updates in the Alpha 7 IV v1.1 include:
