Too many user interface defects

I like the way you define your camera bag contents (cameras and lenses) to make it easy to pick the ones to do calculations for. For each lens you enter the focal length, max apperture and min focus distance. Select your camera and lens from you bag then go to the home page to calculat DOF. But with the units set to Meters the closest distance I can set is 4 meters. To set to anything less I have to change the units to CM and then change it back. It should not be this hard. I have one lens that opens to f/1.2 and I setup the lens for this apperture in the bag but it will not let me set the apperture to less than f/1.3. DOF is critical at this wide apperture - it is unacceptable to not let me set the right appature. I will not be able to use this program. I wish I could get my money back.
