HiYa
just had the opportunity to do some lens testing of the standard canon lens that came on a 300D with some of my lenses, and found something interesting. I took some shots with my 50 f1.8 (series 1) which normally produces very nice contrasty images on slide film, noticably more so than the zooms (35-70 series that came with my 630 one and 28-205) that I've got. However I didn't see that much difference when looking at the images.
I thought that perhaps the reason was the the CCD does not capture the same MTF that film does, so its its (to make an analogy) like changing 16bit CD audio (44.1KHz 16 bit) or DVD audio (96KHz 20 bit) onto MP3 ... detail is lost.
So this makes me feel that there is a reduced need for the high quality optics in lenses like L series lenses for use with Digital bodies. Perhaps the D1D may make a difference, but I'd not be confident, as the pixel density per square mm on the CCD is about the same I thought. So it may make a bigger image, but a crop of a central portion would be the same ... with the same lens.
for those who are interested, I've placed both images on my webserver as raw format

all photo details are contained within the images :D
be careful, they're large :D
