Okay, I'm forced to show my ignorance here... what exactly is an ICF filter?

And that doesn't happen a lot, now does it Chris? Actually this is
a good thing... I must confess I don't know either... heh.

ICF Filter
this is a fiter which lets through the visible light to the CCD and filters any infrared light which is not visible to the human eye. This allows the picture generated to look normal.
That is how I understand it at least. There is supposed to be a blueish ICF filter built-in but if I were to remove it would I be able to replace it with a 72mm one on the front of the lens. Any help is appreciated. Thanks. Russell |

infrared clear filter? heh.. just a guess. Well, if such a thing is
in there I suspect it will be of at least good-enough quality. I don't think much people are complaining about the lenses (especially at there price range). You can always put professional 35mm lenses in front of the XL1 if you want to be sure though (expensive though!).

Hi,
To the best of my knowledge the filter is built into the CCD. It is very precisely glued or fixed into place and cannot be removed. The filter and the CCD are a complete assembly. If you want to achieve an infrared look there are plugins for photoshop that can accomplish that. Jeff |

Didn't Sony add one to their night shot camcorders after they found the see-through-clothes problem?
No mention of ICF in the standard Canon XL1 IS lens documentation. But I note that the lens does have 16-step zoom speeds (range 1.7 to 60 seconds). The ND filter is 5 stops. Optical resolution is specified at 100 lines/mm center, 64 lines/mm at the edges. 12 elements (2 of which are aspherical) in 10 groups. Also has a protective glass at both ends. Current draw is up to 500 ma. It contains a microprocessor! |
