having shot for years with a Betterlight scanning back, where there's no IR blocking between the lens and the sensor, and requires a filter all the time (unless doing IR images), the thought of having the IR cut filter on the Leica doesn't seem that daunting.. in fact.. for someone who does a lot of IR imagery, it's an advantage.
