Hi Hike

Look at the camera review section aswell.

32 gb seems to be the largest you can use, ...... but you could try

The latest firmware update allows sdxc cards but what amount I do not know..

Hope that helps.

With the latest firmware, SDXC cards should work. You will need an SD or SDHC card to run the update if you haven't already done so.

As Adam wrote, it should work. Since the camera's max write speed is 25mbs, there's no need to buy a super fast card unless download speed to your computer is important.

The question involves more than speed.
In Summer 2019, I had problems with 64gb cards - I eventually discovered that cards larger than 32gb seem to be formatted using exFAT, and my Pentax K-30 and KP cameras eventually have problems with it, so lately I've used only 32gb cards in those cameras. Interesting, my Pentax Q-7 seems to have worked fine with a 64gb card since then.

If you use SDformatter, they can be formatted to FAT.

Perhaps you have a hardware problem because the KP itself formats SDXC 64MB cards using exFAT. That type card is all I use in my KP and K-S2. Never a problem and the OP should have no problem either with a firmware update. Using SDHC FAT formatted cards limit performance.

'FAT' is an international standard; 'exFAT' is a proprietary standard introduced by Microsoft because 'FAT' is limited to how many locations can be addressed.
Honestly, 32gb has not turned out to limit what I photograph.
Your experience may differ - I raised this issue only because I stated that we have to look at more than speed, which I still believe to be true.

Not any more:
"exFAT (Extensible File Allocation Table) is a file system introduced by Microsoft in 2006 and optimized for flash memory such as USB flash drives and SD cards. exFAT was proprietary until 28 August 2019, when Microsoft published its specification. Microsoft owns patents on several elements of its design."
