Subject: [Leica] Weird: DMR and TTL works!

If I remember correctly the reason why TTL hasn't
worked on digital cameras in the past is that the
reflectivity of the surface of the low pass filter is
very different from film, presumably varying in some
non linear way that nobody has so far been able to
adequately compensate for. Maybe now, without the low
pass filter, the sensor surface is more like film or
maybe, in the test pix in question, the error is
negligible and under some other conditions the
incorrect exposure may result.
