Ever wonder just how much depth-of-field you have at any certain focal range? Go here, input your camera, focal length, aperture, and distance to subject, and it will tell you exactly where your focus should start, end, and how much total distance will be in focus. It's very handy information to have.
I really like this advanced calculator: http://eosdoc.com/jlcalc/
It calculates and displays a lot pf useful information, including the bellows factor, which is important for a lot of situations. The only thing I can't figure out is how to calculate for 1/3-stop apertures.
I recently used it to calculate that all of the following camera have the same 16.4-foot focus distance, 40 degree AOV, and 6.7 feet DOF:
Scarlet 2/3": 14mm f/0.9
4/3" DSLR: 24mm f/1.6
Super35: 34mm f/2.2
Still FF35: 49mm f/3.2
645: 76mm f/5.0
617: 220mm f/14
Having a version of this that I could run on my PDA (while it's not networked!) it'd be super cool.

DOFmaster (first post) is available on that site for the Palm and iPhone.
I like this DOF calculator http://www.davideubank.com/Also available for Palm & iPhone....for a nominal charge ($20), but well worth it.
