Sony has released Firmware Ver. 1.10 for its α7 IV (ILCE-7M4) mirrorless camera after pausing the update due to issues with some associated products.

The update should only be applied to cameras with firmware Ver.1.05 already installed and camera owners who have already installed the earlier version of the latest firmware, which became available last month, should set RAW File Type to Lossless Compression (L) to resolve the previously identified issue. The new firmware provides the following benefits and improvements:

  • Allows the user to select M and S sizes in addition to L when using the RAW recording lossless compression method
  • The shutter speed and ISO sensitivity settings dedicated for flash photography can be retained
  • Adds the Touch Shutter function
  • Improves the accuracy of the Eye AF feature
  • The camera’s serial number can be recorded in the metadata in the movie files
  • Note: Where the Write Serial Number option was set to On before the update, the Write Serial Number (still image/movie) will be set to Off after the update.
  • Improves operability of Wi-Fi connections
  • Adds a 1 minute setting to the Power Save by Monitor menu
  • Fixes an issue where the viewfinder display may not be brightened according to the ambient brightness
  • Improves the accuracy of the Eye AF feature
  • Fixes an issue where you may not be able to take photos when using a SEL2860 lens
  • Improves the operational stability of the camera.
