ive been using the sony sxs adapter and the sandisk 32gb class 10 extremes with no issues. ive been hesitant to go to the 64gb. but have a big all day job that would probably necessitate using the 64s. anyone use them with no issues on a regular basis??

Depends if you are filming a "one hit wonder" or something where you can re-shoot a take if the camera / storage locks up or something.

Jim,
I use Sandisk 64 gigs all the time with no issues. They are great for long conference days.

I use them a lot in music festivals as I don't have time to dump until the end of the day sometimes.

I'm using them primarily in Sony EX1R's and lately Sony EX3

thanks al.
im shooting an all day recital from 830 to 630, they average 1 1/2 hour each with 30 minute breaks, but the last one is 3 1/2 hours,no breaks

You don't state what camera and firmware.

EX1/EX1r and EX3 cameras need to be properly updated to accept 64GB media.

As well, the XDCamEX line spans cards reliably - just remember to use the appropriate Sony application for ingest, not just dragging and dropping.

EX1R version 1.30

You should be fine for both 64GB SDXC cards and XQD cards. There is firmware 1.31, (which I have installed) but the changes are minor.

you mean sdhc? sdxc not familiar with that

SDXC are the indication for SD cards above 32GB. SDHC stops at 32GB and 64GB cards are marked as SDXC.

Honestly, I think if you are on firmware 1.30, a XQD card would yield far better reliability compared to a SD card. I've had problems with SanDisk Ultra SDXC cards and my EX1R due to too low write speed.
