We need to find out more about the lens coding... Which codes for which lenses..... Didn't someone offer to compile this list? Frank Filippone red735i@earthlink.net My guess is that every lens absorbs some amount of IR, and that the lens coding will tell the firmware how much IR made it through the lens.
