comment What do I need to make my own camera stand with a 40" horizontal arm?

A 40" horizontal arm is going to be very unstable unless it's very massive. It'd be much easier engineering if you could support the horizontal arm from both sides (making it a bridge,not an arm).

comment Why do depth of field calculators show *more* DOF for larger formats with the same lens parameters?
"I removed them and changed my answer" well that's kind of a bummer. Although mattdm summed up the error in my thinking so nicely I had to give him the right answer honors, you're pictures illustrating that DOF doesn't really change with the sensor size were very appropriate.

+1 thanks. Your photos nicely illustrate the errors in my thinking.

+1 That's a great answer Stan but I've got to give the checkmark to mattdm for identifying my erroneous thinking so concisely.

Your first sentence nails it. (face palm for my own sloppy thinking)
