with really good lenses and film and processing 35mm can exceed the resolution of a 6MP non- foveon APS digital sensor. I don't think there is any debate on that....

Thanks for the link, Rob. My concern is, that he/she measure exaosed and developed FILM, not prints, that can never really reproduce what's recorded. In real life I believe there's no big difference, resolutionwise between prints or scans from a 6 MP digital camera and files/prints made freom 35mm negs. My test show this very clearly. If there were, I'm sure I would use my filmcameras more :-).

Remember that the each pixel records the luminance of either red, green or blue, the luminance of any other colour at each point is a calculated guess. Interpolating to produce an image with greater final pixel dimensions will provide no more data it just produces transitional values pixel to pixel that are calculated based on the measured data. Regardless of the factor of over- sampling (interpolation) you will still end up with approximately the same actual line pairs per mm but they will be spread over more pixels. > So, as far as I'm concerned, a 200 ASA superia and a 35mm pentax > camera and lens > can't really outperform a 5 MP digital camera.
