Use DOFMaster to calculate the depth of field in your photographs. You'll be able to select the lens and f/stop combination that provides the zone of sharpness you need. Use it to calculate the hyperfocal distance for landscape photography.

DOFMaster calculates total depth of field, near focus limit, far focus limit, and hyperfocal distance.

Depth of field can be calculated for any film or digital camera. Select a pre-set format (e.g., Canon DSLR, 35mm film, compact digital, Super 16, etc.) or a custom circle of confusion.

F-stops range from f/1 to f/64, with 1/3, 1/2, and full stops. Focal lengths range from 3mm to 1200mm. Use feet, meters, inches, or centimeters for input and output.

WASTE OF MONEY!!!! Another failed app costing apple users their hard earned money. Sure it's only a couple of bucks, but when you multipy that times all the phony apps on the App Store it adds up after awhile. It also gives you that creepy "just been had" feeling that makes you want to take a shower. This is one of those "creepy just been had" apps that Apple shamelessly allows to be sold to their loyal customers. (Shame on you Apple). Your phone is starting to give me the creeps too. Anyway, this app falls down the first second I opened it. It only allows me to select the default settings because it's totally unresponsive to touch. When I try to select "Nikon" it just lays there flipping me off and laughing at me. Nice. Nothing like being disrespected by a freaking app. Real funny DOF Master, you guys got my money for nothing more than a graphic image on my phone which I probably won't even look at all that much. Kinda worthless really when you consider the fact that I purchased this as a DOF calculator. Oh well, jokes on me I guess... Is there anyway to give this negative stars?

Almost perfect! v1.0.1

This is a simple to use app that isn't cluttered with a lot of bells and whistles. It does just what it was intended for - gives you the DOF/Hyperfocal distance based on your input. I do agree with others that it should have the numeric keypad as default for inputing your focus distance. Also, it would be nice to be able to toggle between the original calculation and the hyperfocal calculation after you press the "HD" button. Other than that it is the perfect app for calculating DOF.

Well Done

Just downloaded this app today. I compared it to a hand help Hyperfocal chart that I owned and it was spot on. HD calcs the correct focus point and the table shows the area of focus as 1/2 of the Hyperfocus distance. Perfect. All I had to do was set it up for my camera type and from then on just input the lens mm, the f stop and you are ready to calculate. Now I don't have to carry around an additional chart.
