I feel the same way about at least getting the information out there, and I see APUG is a repository of collective experience, so I do share and appreciate your attitude. Looks like you really are in Ferndale... I thought it might be a joke on the old "Ferndale Tonight" Martin Mull TV show. You're lucky to have actual camera stores nearby, and two at that. Hope you can find a sample to look through. Turns out I'm not that far away by some standards, a bit SW of Cleveland. If you have no luck getting your hands on the C/V stuff, maybe we could meet halfway and you could shoot a roll with my wides after they return home from loan.
I was also finally relieved of parental duties long enough to sit down and find my DOF spreadsheet and run the numbers. (My wife is on the schedule from hell.) Here are the hyperfocal distances in meters for a 21mm lens with a circle of confusion of 0.025mm, a slightly conservative calculation. Near edge of focus is half of hyperfocal distance.
Aperture / Hyperfocal distance in meters
4.0 / 4.41
5.6 / 3.15
8.0 / 2.20
11.0 / 1.60
16.0 / 1.10
22.0 / 0.80
So even wide open with the C/V 21mm at f:4, you're covered from 2.2 meters to infinity, and at a near optimal f:8, you're good from 1.1m to infinity. Back it off a bit if you don't need infinity, then point & shoot, and don't worry a lot about perfect focus, or just guess-timate focus as David mentions and you can hardly miss.
