you can have a look at a APP for smart phones , called DOFmaster..it allows you to input your variables such as MM of the lens and it aperture..it will give you the Hyper-focal point in its equation as well as giving you the amount of DOF if you aren't using the hyper-focal point

good to use in landscapes..if you want everything in focus
ALSO. The hyperfocal distance is affected by sensor size as well.

To the OP. I suggest you, as a beginner, start looking at the New To Photography section of the Ausphotography Library. Work through it, and as a beginner, just focus on the subject of your shots. Get all the basics down of aperture, ISO, shutter speed and leave all the other stuff alone for now. Trying to learn all about the differing metering modes etc is something you can work on down the track. To much information at once will just confuse you.

Take it slow and learn each camera function, one at a time, and only move on once you understand the one you are learning, and slowly build up your knowledge and skill base. Photography is supposed to be fun and enjoyable, trying to learn to much, to quickly, will take away the fun, and frustration will come along and that is when people give up.
