I agree with you on the profit that can gain with a camera system, the
body is just a small part. But for the flash, old TTL is hard to work
with a CCD sensor. It need a completely new flash control technique,
like the E10/20 case, a preflash is made every time you trigger the
shutter, after evaluating the light intensity that reach the CCD a
signal is sent to the flash to command for proper power. Unlike the
TTL flash in the OM system where a flash cut off signal is sent after
proper light energy is reached.
