Subject: [Leica] Consensus (? on LUG) on IR filters on M8

Vick,

If the filter does degrade the image it is extremely slight, maybe the big 
item is possible reflections, but it is no worse than useing anyother filter.

If you shoot B&W, then no reason to get a filter at all.  The 2 free filters 
from Leica take about a month to get, once you register for them on their 
site.
It is evident in about 10% of scenes at best, and can be removed in post 
processing.  Personaly I just keep the filter on the lens and have forgotten 
about the issue.  I have seen no negative effects to date.

Unless you shoot mostly 28mm and wider the coding is a waste of time and 
money.  I have a pre-asph 35 Summilux which cannot be coded and have seen no 
cyan shift at all.

Buy the M8 , get an extra battery also.  Buy several SanDisk Extreme III 2G 
SD cards (Thats what I use and have had no problems with them) and have fun.
