Hi, which of the above filmstocks have the finest grain and the greatest resolving power

 

The data is on the Kodak website (MTF Curves):

I think there is an error on MTF curve on your Kodak link for k25, the MFT is displaying 100t 7248/5248 film stock and not k25. So is k25 the winner of the resolving power contest between k40 and 7245?

On more recent films, Kodak is publishing MTF data for all three colors, rather than a single "neutral" curve.

 

Yes, K25 was discontinued several years ago.
