Do you have a Microcenter nearby? Their store branded cards are cheap and work fine in everything I've ever tried. If you don't have anything laying around to use, I'd recommend buying a micro SD, they typically come with a full size SD adapter, and then you can use it in other things should the need arise. Logs take up very little space so you don't need a big card. 4GB would be plenty, but if you're buying one get at least 16-32GB because they are incredibly cheap and you may as well.

SanDisk ultra uhs-1. Mcrosd were on sale at Amazon and adorama earlier. I got 64gb for 15 bucks. There is no way you need anywhere near that much storage though. Seems like the microsd go on sale more often and they almost always come with an adapter.

UHS-1 Class 3. so 90 MB/sec both read/write.

the ultras is only like 10MB/sec write. if you want SanDisk get the Extreme Pro.

This quick video I did demonstrates the write speed between the two:


Those are roughly 30-40MB files it's writing each shutter accusation once it bumps up against the 15 shot buffer.

It probably doesn't matter for the MS3 logging, but you might as well put in the better card you can.

MicroSD cards read/write even slower--even the same model/product line.
