I've recently purchased DOFMaster for my iPhone. In calculating the hyperfocal distance, I need to enter the focal length. Is this the focal length I read off my lens, or the adjusted focal length in 35mm terms? Can't find this information anywhere on the DOFMaster website.
Clarification: My Nikon camera has a 1.5 image size factor. So, when my lens says 18mm, its actually 18x1.5=27mm (in 35 mm terms). In DOFMaster, do I enter 18mm or 27mm?

Since that app does not account for crop factor you are probably going to want to use the 35mm calculated focal length.

ok, got the answer. Actually it *does* account for crop factor when you select the appropriate camera. So, I need to enter the focal length that I read off the lens barrel.

Is the app any good?

Yes, its great! It tells you the hyperfocal distance based on your camera, aperture and focal length, so that you can get landscapes where everything is in focus, from a few feet to infinity. The trick is to measure that distance and focus on it, as some of my digital lenses don't have any distance markers on them!

I must be old school I actually read the markings on my lenses
