At this late stage I have to ask what it is that you are looking at. If it is the top display then the buffer holds 15 shots whether 12 or 14, compressed vs lossless compressed in FX mode(pressing shutter button halfway, r 15). With auto distortion control on r =10, so the buffer has been limited. So with auto distorion off and r=15 12 bit compressed the stated # (27)of shots give or take (depending upon file size) will be shot before the buffer fills and the rate slows. And now I have learned something new. Thanks for the question!
