Hi Ken

The flange focal distance for PL is 52mm. I don't know if that will
be right with your C-mount S8 camera, which one is it ?

However, and I don't know exactly the focal length of Lensbaby -
google search & it seems ~ 50mm -- I don't know that the effect will
work on a S8 camera given that rather long focal length for the S8
format; you are only using the center of the image this lens forms so
how would you see the out of focus edges in Lensababy's selective
focus properties ?

(It can work with small format DV & HD cameras _if_ you use P&S type
adaptor which focusses a 35mm (motion picture) size image on
groundglass or what have you.
