Wha-tever werks! Actually, I found it useful to choose a target that had
bits of nearer and more distant material, along with a lot at one distance,
both for checking focus accuracy, and for spotting the tendency of some
lenses to render the corect-focus subject properly, but not the out of
focus areas (not symmetrically/equally unsharp).
