Thanks.

Yes, the built-in filter is a 720nm one, but a very thin type, only 1mm. This reduces the amount of AF adjustment required for IR quite a bit, you don't even need to do AF adjustment on some lenses like DA21, M20/4 and etc.

OP used a filter in front of a lens. When taking IR photos w/ K10D this way, the exposure time will be very long, sometimes even above 10 seconds. While using a converted IR camera, the exposure time will be much shorter, pretty much like using a normal camera. But of course it's quite a bit cheaper to just buy an IR filter instead of a converted camera
