Sony has released Firmware Update FW 3.20 for Sony a7RII and FW 2.10 for Sony a7SII which add the ability to record XAVC S video to SDHC cards in addition to previously supported SDXC cards.

Sony firmware updates are cumulative so if you missed previous update(s) you will also get firmware improvements from the updates that you skipped.

Firmware Update Benefits:

• Allows the camera to record XAVCS format video with an SDHC card in addition to SDXC card.

Notes:

• When an SDHC memory card is used in XAVC S format over long periods, the recorded movies will be divided into 4 GB files. The divided files can then be integrated into a single file using the PlayMemories Home software
• Shooting movies in XAVC S format requires SD Speed Class 10, UHS Speed Class U1, or faster
• When recording at 100 Mbps or more, UHS Speed Class U3 is required
