What is interesting is when you look at the Leica users group they are

That is just about as far from the truth as it is possible to get.

I read four Leica groups online and all are at best ambivalent about
the Leica M8. None of the groups has anything remotely resembling the
enthusiasm that so you inaccurately describe. On two of the groups,
the M8 is hardly discussed at all, because after the initial
excitement of the first digital M there is so little to say about such
a flawed camera.


Not sure about the flaws bit. But the feedback I'm getting
from other Leica users is precisely that. A lot have tried
the M8 and gone back to film cameras. One pro is even
gone and got himself a Zeiss ZM to replace his M8
trial. He shoots L glass for fun and 1dsm2 and 5d
for his gain work.

I think L needs to fix that sensor problem, without
filters, and pronto. Or do something about the price.
One of the two or both.


The sensor problem cannot easily be solved, if at all. The extreme
angles of incidence of light rays, thanks to lenses whose rear
elements come close to the film/sensor, mean that there has to be a
combination of (1) a thin cover glass, (2) no anti-alias filter and
(3) offset micro-lenses. A digital M mount rangefinder will not work
properly without all three in combination.

The M8's infra-red problem (magenta casts etc.) is a direct result of
the thin cover glass. In DSLRs, the cover glass is of the correct
thickness to virtually eliminate infra red at the sensor. The M8 has
a cover glass that is only half the correct thickness, hence the need
to use a UV/IR "hot mirror" filter with all lenses.

However, the UV/IR filter causes problems of its own, with moderate to
severe cyan fringing as the ange of view of the lens increases. M8
users with 24mm or wider lenses will need to remove this cyan fringing
in post-processing.
