I'm looking for a DOF app that's accurate.


Even if you can calculate the hyperfocal distance to four significant digits "accurately", the value depends on a bunch of unreliable assumptions, you can't focus precisely at 18.46m without the careful use of high-precision measurement technology, and even if you do all that correctly, you won't get everything from 9.23m to infinity "in focus" because it simply doesn't work like that. You're right, I'm a grumpy old skeptic.
