Originally posted by vrrattko DA 70 is very sharp lens, I had one alongside with FA77 and K85...and I have to watch photos at very large magnification to see that K85 is marginally sharper (FA77 was not). So taking in account also lens sample variety, it may happen that old lens could beat DA limited, but it would be narrow. The question then is if you have lemon DA70 or extraordinary M100.
Testing Da 70 vs. M100 without having a M 100 is a bit odd.

For the Thread starter:
Good lenses will not be worse on aps-c
Whats really a difference from the film days, is the angle of view because the crop factor.
The M28 f/2,8 used to be a nice wide angle lens, with nice color.
On aps-C its almost a normal lens, and because of that the colors are a bit less rich.
The 50, 100 and 200 would be from normal to telelenses on film.
They are tele lenses on aps-c
colors app. as in the film days.
THIS IS MY HYPOTHESY and not very well documented.
I myself am not using the M-28 anymore. It does not work as it used to.
My M and A 50, 100 and 200 are as good or better than in the filmdays.
So if you want to test my hypothesy, try an A or M 50/1,7
