Thank you for these tools. DOF master does take a lot of guess work out. My next question is how to set the lens for hyperfocal. Is it as simple as just lining up the infinity make on the scale on the lens (16-35)?

You should line up the focus mark with the hyperfocal distance you've found.
For the sake of asking, any reason you aren't using autofocus on such a fine camera and lens?
We're a Canon/Profoto family: five cameras, sixteen lenses, fifteen Profoto lights, too many modifiers.

Hyperfocal distance is F + (F^2)/fc where F is focal length, f is f number, and c is the diameter of the circle of confusion. The camera knows all of these quantities, so it could do it for you. Maybe the problem is that in real life, the circle of confusion depends on what the photographer wants in a particular situation. But then, if there is confusion about the circle of confusion, how do DOF calculators work? (I just looked at DOF master: it seems to assume the cof is about sensor size / 1200, which may be some kind of standard, but seems a little crazy to me)
Some of my technical friends who don't actually take pictures are surprised to learn that canon DSLRS don't have functions to do things like focus on the hyperfocal distance, focus bracket (that I know of), achieve a specified DOF, etc etc.
