You should not use the FL-D filter with a digital camera. You can easily compensate the white balance, either by setting "fluorescent" or (better) by shooting a custom white balance. The FL-D filter will do the same thing on a digital camera that it did with film. But it'll cost you a stop or two (don't remember) in light loss.
