didn't notice your link the first time Hank - interesting and thanks.The sort of finders golfers use are useless for focusing guides. The meter I had was accurate to 1mm from close up to farther then I needed. Even the cheaper smaller meter I linked to is good for 1/8th of an inch accuracy good enough considering the markings on the focus barrel. You don't need anything like that kind of accuracy to try a figure what club to use on a golf course.
Still these are wide angle lenses being shot stopped down not a long fast lens wide open -its more for moving your hyperfocal point to optimize your zone of best focus.
