[ . . . ]
I had always been under the impression that the
Hasselblad CF100 Planar was considered their
most accurate and highest resolution lens . . .,
generally speaking, with a very desireable M.T.F. curve .
1 / Do I understand the notion "sharpness"
in a wrong way ??? (though i know the CF180
"rates up" with the few "high performance"
lenses now available "off the shelf" ; it remains
a more than 2X normal lens, a lot by my usual
preferences over the years ). . .
2 / Is there some "chart" or system to help rate
the ACUTANCE / EDGE DEFINITION
of a given lens, objectively ?
Or RELATIVE to others designs ?
Would this relate to some "threshold" point
in a M.T.F. curve, even subjective ?
Thank you,
Andre Jean Quintal
