It would seem that Digital is similar in that larger sensors have an advantage in output over small sensors.
I had the Canon EOS1d which was a 1.3cf while rebel was a 1.6 and the top line were 1.0 since they were roughly the same size as a 35mm neg.

My current APS C sensor does just fine for what I am doing BUT, I'd love the adaptor for some GREAT glass. Prime best but zoom if I must. SONY lenses are only OK, except for the 35mm 1.8 whichis pretty good, but 3x or 4x MORE expensive than the Canon 50mm 1.8
The Macro in the 'E' mount is also very $$$, even more than the Canon glass and probably not as good. I'm going back to manual focus / exposure.

I never used Tri-X professional, but always just color print film in my 120 / 35mm (It'll take either) Yaschica 635. A terrific 35$ Garage Sale Find.

ONE of the main reasons for the apparent sharpness of some B&W films is the LIMITED response to full-spectrum light. As it turns out, getting a lens to FOCUS at all 'frequencies' from Deep Red to the Bluest-Blue is a problem. Apochromatic glass is tuned to be in focus similatniously at 3 wavelength.
Orignal B&W film may have been mainly sensitive to Blue and less so at yellow and green wavelengths. Later RED sensitivity was added and I think this was the origin Of PANCHROMACTIC film. Like PlusX-Pan.

You can view some of this effect by taking a digitial or ANY scanned color image and removing ANY 2 of the 3 primary colors. You'll end up with a monochrome image of greater apparent sharpness
