K-7 Burst 4 shots only

Hello, I am wondering if anyone can give me information on how to increase the buffer size on my k-7 because it will only shoot 4 shots and stalls. I used the same card I have in my k-5 that will take 15+ before stalling. I shoot Raw I am just wondering if this is a limitation of the k-7 or if something might be wrong with it.

thank you,
Brian

Things you should check:
lens correction, shadows highlights correction, any other in camera image processing function.
they all affect the speed of burst shot and therefore the speed of the buffer.

The K-7 should be able to do 14 (DNG) or 15 (PEF). Make sure firmware is updated to 1.11 for SDXC card support if that is the type of card you use.

Are you using a class 10 or faster card? Your card should have a write speed of 25 Mb/s or higher to outperform the camera.

Like others have mentioned though, check to see that distortion corrections are disabled, as they take forever to process.

Also make sure shutter speed is reasonably high. I was caught once until I realised I was experimenting in the lounge room with low light and subsequent long exposures impacted on the frame rate.
