[Leica] Glass IR cover on sensor

[red735i at earthlink.net (Frank Filippone)]

And more so since the camera is purported to have iris - focus compensation.
you can correct anything if you can model it.....and a flat piece of glass,
with a known lens that has been "mapped" can easily be compensated.....

.....if the entrance angle is not  
too extreme, moves the focal plane back about 1/3 the thickness of the  
glass. This might introduce a problem is switching lenses between  
cameras. The shift in focal plane would be quite small, about 1/3 mm  
but that's enough to rile RF camera users. Of course with DSLRs or  
autofocus the point is moot.
