A free program for Android, by Javier Cancio.
This is a very useful tool for any amateur and/or professional photographer who wants to know the maximum possible distance from his/her camera to the subject. It's also great for any photographer who wants to know the closest distance that his/her lens can be focused without losing resolution.
There are many factors that can affect the resolution of a photograph, such as the camera, the lens, the lighting, etc. The most important thing is that the lens must be focused. If the lens is not focused, the resolution of the photograph will be lower than you can possibly get.
When you use the app, you will be able to calculate the hyperfocal distance in meters, feet, yards, and inches.
