Clarification - Sigma body filter also for UV and IR.

No, the sensor has a protective glass cover, like (I believe) all sensors in cameras but the body insert filter (to keep inside free of dust in the main at least) can also be removed in the SD9 and SD-models to and including the SD14 to then allow for IR captures - a very simple and useful feature. This "protective" body filter that effectively seals the body interior for the models mentioned is also a filter for UV and IR rays.
