Originally posted by WalterGA Recently bought an 8Gb, class 4 card; today ordered a class 6, 16Gb card, both used in new K20D. Does the K20D write fast enough to utilize the faster card?
I was advised by my Pentax repairman and dealer that my K10 needed to use a 133x card (20mb/s). What I found using slower cards that in burst mode the camera would take 4 or 5 shots and then pause for the card to catch up. When I installed a 133x card the burst mode didn't pause. I think you should use at least a Sandisk Extreme III card or it's equivalent to get maximum performance from your K20.
