And the RAW buffer is 8 frames if we believe the official specs from Pentax Europe AND America.
From the OFFICIAL source(pentax.jp/english !):
Max. 7.0 fps, JPEG (16M: at Continuous Hi): up to 22 frames, RAW: up to 8 frames
Max. 2.0 fps, JPEG (16M: at Continuous Lo): until SD Memory Card is full, RAW: up to 12 frames
SAFOX IX+, 11 point (9 cross type focus points in the center)
BUT if I believe the google translation of the Japanese version on Pentax.jp it is:
up to approximately 7.0 frames / sec, JPEG (16M: ★ ★ ★): up to 30 frames, RAW (PEF): up to about 08 frames, RAW (DNG): up to approximately 8 frames
(2) up to approximately 1.6 frames / sec, JPEG (16M: ★ ★ ★): to fill space on the card, RAW (PEF): up to 10 frames, RAW (DNG): up to 10 frames
Strange....
