'The number of electrons collected is linearly dependent on light level and exposure time ...'. It is a pretty basic electronic theory of integration. The rest of the sentence was more interesting... ".....and nonlinearly dependent on light frequency..." ( or so I remember the words...) In this case, in my reading, exposure time for the M8 is the open digital gating timing. ( or could be and is the mechanical shutter timing on say the M3). How does the M8 shutter work at speeds of 1/250 to 1/8000? The same way it works below that speed... the gates open, the gates shut for the required timing. You do not need a slit ( or any other kind of mechanical ) shutter, except for this multiple flash mode with fast shutter. There is nothing that I have read that states the digital timing of the sensor array can not operate with a minimum gated exposure time of 1/8000 of a second.. after all, the light is pretty bright to use that shutter speed......and amount of light is all that counts. Read the email I will send out later.... It all sounds logical to me, but you never know what Leica will do / has done, unless you get to have that open discussion with them....
