[QUOTE="pforsell, post: 704301, member: 7240"] Check your user manual if dropping the JPEG saves any buffer space. Going from lossless 14 bit to lossless 12 bit increases the frame rate from 5 fps to 6 fps and increases the buffer from 18 to 27 images. Hence, 12 bit lossless gives 27 images at 6 frames per second allowing a 4.5 sec burst. These are the best case scenario numbers. Things like noise reduction, vignette correction, image copyright etc. all eat into the buffer depth. Please refer to the manual for details. I recommend you make a few tests to see if the 12 bit mode is much worse than the 14 bit mode. Mostly you'd expect to see the differences in the deep shadows. In many cameras the 14 bit mode is just a vanity mode doing nothing useful, but forced to be included in the camera specs by marketing department. Make a test, it's possible the 14 bit mode is just a waste of space. Slicing a bread into 14 slices instead of 12 gives no more bread, if nothing else changes.
