Good point there!
Also, is the camera being moved or, are you shooting all of these from the
same distance?
With a large enough newpaper sample or samples, you should be able to test
all of the lenses from the same distance which, I think is important.
With the wide-angles, to fill the frame, you would have to be much closer
and, they are harder to focus and, would have less depth of field.
I think that you should choose the closest subject distance that all of the
lenses
can focus and, go from there. Or, at least choose a reasonable compromise.
On the 35-80 that you liked so well, what focal lengths did you test it at
and,
did you zoom in to focus (of course you did - who wouldn't).
Same with the 90mm. Easy to tell focus, far enough away to have some DOF.
I think C.H. could be onto something here...
If they are "soft" all over then, something is probably wrong with the
testing procedure.
