Subject: [Leica] It ain't alright.... "Fix it in SW"

In response to BD's email about the M8 magenta cast....

I think that in today's marketing and sales driven marketplace, digital or 
not, shipping without bugs ( known or not) is uncommon.
You must meet certain deadlines.  Bad as that is, it is reality.

However, the fact that you must use a piece of glass in front of your 
lens.... note the operative word here is MUST.... is
unacceptable.  ( No, I am not starting problems, it is an opinion).   If the 
sensor is slightly more magenta sensitive, the glass
protecting filter should have been coated to attenuate the magenta rays.  ( 
that is what the applied filter will be doing).  It is a
matter of a coating on the glass plate.  It does not require more glass over 
the sensor, thicker glass, SW interventions, or other
"extras".  It is a VERY thin layer of deposited vapor on the glass cover 
plate.  It takes an optical engineer a few hours to
compute, a manufacturing engineer a few hours to try it.  It is not brain 

It should have been done, it needs to be done, it is unacceptable that it 
was not offered as the "fix", with free retrofitting to
early adopters.

But Leica had to meet deadlines, and Leica does not want to be in the 
business of sensor replacement.  So it was not offered.

Kodak did not screw up, Leica did.  They should have tested the sensor over 
the optical BW, found the error ( or they did find the
error and decided that the market would not find it or that it would be 
fixed in SW) and offered to fix the issue in production
sensor glass cover plates.

It is the only acceptable solution.....

How many of the LUG have backgrounds in Technology and heard those dreadful 
words... Fix it in ....SW?
