I have downloaded pages from http://adaptall-2.com/lenses
and would like to know the following:-
When comparing lpm from the tables illustrated, how critical is the difference between.... RESOLUTION at xxmm at 1:48 magnification
and... RESOLUTION at xxmm at 1:50 magnification?
I appreciate that what makes a 'good' lens is not always its resolving power and that there are other considerations but my curiosity
is aroused by the difference between say... the Tamron SP 70-210mm f/3.5 (#19AH) and the 70-210mm f/3.5-4 (#46A) in relation to the 'Modern Photo.' quoted charts contained in the tests/descriptions.
Can anyone shed some light on this please?
