(ones not modified by removing the IR filter over the sensor.) With the Nikon D200, which is very very insensitive to IR, handheld IR shooting is virtually impossible (without significant motion blur.) Note also that having a separate viewfinder is an advantage. With DSLRs you have to keep taking the filter on and off to frame and focus. I have not undertaken a comparison of the actual shots.
