[Leica] Digital R8/9 question

[summarex at hotmail.com (Javier Perez)]

Hi Everyone.
I was thinking. D SLRs have enough clearance between the focal plane and the 
shutter to accomodate a protective glass in front of the sensor which 
usually doubles as a filter and because it's usually far enough in front of 
the plane, small amounts of dust don't show up, Since the R8/9 is a film 
camera I was wondering if Digital R users have had any problems of the sort 
that require frequent sensor cleaning or better said, does dust show up more 
on a digital R than it does on a 1D or Rebel.
Very curious
Javier
