Build
Fast and smooth focus
negative:Outer image sides and corners are very soft, as well as all left side on this particular lens.
Cannot use std filters
Sun flares quite bad, reflecting inside lens to soft/blur opposite outer edge.
Does not like shadows.

comment:Very inconstant results with this lens
F8 and F11 produced best results at 17mm
Post processing to a limited, but poor quality cannot be fixed.
Did tests in studio first, then outside in in mid early morning.
Will not be keeping or using
