Needs improvements

Not very useful with long focal lenses. The developer needs to accept the fact that this app for the most part will be used for manual adjustments. For example, I have a manual zoom lens (non-TTL) that covers focal lengths from 650 through 1300. There is no way to calculate a precise hyperfocal plane because the app doesnt cover that range smoothly. The app should cover long ranges in non discrete fashion, because long glass has a very shallow depth of field requiring precise calculations. Forced extrapolations or interpolations just defeat its purpose.
