Sony has issued new firmware for the Sony A7rII and A7sII, allowing XAVS S video to be recorded on SDHC memory cards.

Before, you had to have SDXC or memory cards larger than 64GB to record XAVC or 4k video on Sony cameras.

I’ve seen people trick their cameras into using SDHC memory cards before, so it was always plausible that this feature could work.

Sony cameras are notoriously bad at dealing with memory cards. The update tells us that Sony is finally looking at how their cameras interface with memory cards and improving upon them.

Hopefully, there are more improvements behind the scenes that fix the compatibility issues Sony cameras randomly have with memory cards; figures crossed. Update: It does not.

This could also mean we’ll see this same update roll out into Sony’s other 4k cameras.
