Does the K-50 make use of UHS Speed Class 1?

or will my older 45 mb/s class 10 cards work just as well?

I can see the k-50 can read/write the cards, but does it make use of their speed?

It will. The K-50 doesn't take advantage of UHS-I and it maxes out at just under 30 Mb/s write speed.

OK, thanks. I was hoping it would take advantage of UHS-1, but I can manage.

I ran a test of the San Disc Extreme (45mb/s read/write), at RAW+large JPEG in a 15 second test, the K-30 yielded seven burst shots, plus 21 more shots for 28 total, flushing the buffer six seconds later. Slower Class 10 cards (Panasonic, Transcend and Kingston) yield the same burst, 21-26 total shots, and take about one more second to clear. I suspect anything beyond the San Disc Extreme will not show faster performance. (K-50 is the same as the K-30 regarding performance.)
