My wife is becoming a pretty good bird photographer with her FZ-1000. She is most interested in "birds in action" and uses the burst shooting mode a lot. I have convinced her of the value of RAW files, so she has been shooting RAW + JPEG. But, in this mode the camera shoots 3 photos and then pauses, sort of removing the benefit of burst mode. If she shoots JPEG only it can shoot dozens without pausing.
Is this a limitation of the camera itself? Would buying a faster SD card make a difference? Her current card says "633x; 95 MB/Sec".
