Shot at 85mm, 120mm, 180mm, and 210mm focal lengths
using f3.5, f11, and f32 at each length.
I do wish that I'd shot f5.6, but these are fairly sufficient.
Lens performs so-so at f3.5 across the range.
Like many zooms of the era, the ends of the f/l range are not really grea.
(Though 210 isn't too bad.)
I'm going to treat this like a 100-200/4.5 or /5.6 zoom and simply
avoid the ends.
With that, results should always be satisfactory.
