Subject: [Leica] M8 Article in LFI

The recent article in LFI about the M8 takes on three major issues:

1) IR - they explain it well and the steps to deal with it.

2) Banding - they say it was fixed in the hardware upgrade

3) 8 / 16 bit capture..

..Well here is where I think they turn on the smoke machine and bring in
some mirrors.
They present information about how the data is compressed by the square root
but when it comes down to it, it still sounds like a form of lossy data

IE, The chip captures 14 bit data, crunches  it to a non-linear 8 bit form,
which is latter re-expanded
to bit to form the final 16 bit image file.

So.. Isn't the weakest link in the imaging processing chain an 8 bit format?
LFI then goes on to say essentially "you won't see the difference anyway"

Anyone care to help on the matter? I am missing the point?
