Just think this was a lot to do just to remove the IR filter.

Aquadeveloper my best guess would be yes.  The IR filter is there to help optimize color on the color cams. As far as I know X10 uses the same lens assembly on all of their cams so all of them have the filter, B&W included.

KDR,

Thanks for the info.

One of the reasons for an IR filter is that simple lenses have different focal lengths for different wavelengths of light.  Since the detector is sensitive to both IR and visible light spectra, filtering out the IR provides sharper focusing with the inexpensive lenses in the X10 cameras.

Charles,

I'm not a 'camera' guy, but did feel they were needed to optimize the
image/optic's.

Thanks,

Yep they do. I had to call them.

The ccd element in the camera's are different qualities also.

Have a few low light cameras that are so sensitive, they can see without any infrared light source when your eyes have a hard time making out the same scene.

I have some cheaper camera's that can't do what the low light camera's can do.

Of course after is gets completely dark, the low light cameras need IR light to see in total dark but they do a great job in very low light levels.

Non of my cameras have the red filter in the lens.

Keep in mind that the CMOS imager in the camera may saturate (especially in bright sunlight) if the IR filter is removed.  If the camera is to be used indoors, then you might be okay.
