ok i am a bit confused on the whole fps. the em1.2 states 18fps on low burst and 60fps on silent shutter. i am using the 12-100 pro so i assume that lens should keep up to the body. i did a burst on both settings, low burst and high burst silent shutter, in low for holding shutter down for 2 seconds it only shot 8fps and in high silent only shot about 18 fps. i looked at the images in camera and looked at the time stamp on them, 18fps from one second to the next second, what shutter speed do i need to maintain to get the speeds claimed, i assume if i am at 1/20 or say 1/4 theres no way to achieve high speeds, is 1/60 min to achieve 60fps?
