Scott and all the others ...
Yes, I was lucky to design the modular concept and to map out a stragegy for digital cameras in those days in 1995.
The S1 System is open for all following Lenses: Leica-M, Leica-R, Hasselblad, Mamiya 645, Canon FD, Nikon, all Reproduction Lenses with screwmounts (with Novoflex-Bellows), M42.
I am acutally still selling the S1 Pro and the S1 HighSpeed. They run perfectly on WinXP, Win2000, Win NT, Win98, MacOS 9.2.2 and require a PC with free PCI-Slot. The actual Software is Silverfast 6.x
The Infrared-Absorbing Filters a by intention separated from the Sensor. This means the camera is originally sensitive to Infrared. The Filters can be integrated in the Leica-R and Hasselblad-Adapter. For all other Lenses it is better to place them in front of the Lens.
Because of the optical design we never had problems with what you call "red vignetting".
The types of filters (we called them IRa = infrared absorption) differ in the strengh of infrared-absorption so that you get perfect transmission for daylight or tungsten illumination with maximum camera sensitivity.
