Simple DoF Calculator for Pc

Tried a number of DoF calculators. Most suffer from inconvenient method to enter data: focal length, distance, f/stop; you have to erase current value, then use the keyboard to enter new values. So slow in practice. Many offer long lists of camera models to choose from; kinda nice but the DoF calulation mostly related to sensor size, not camera model. Likely you only need to do this once, though. Many cameras models use the same or equivilent sensor. And lastly, the DoF formula is based on a specific value for the circle of confusion (CoC). (In fact when you pick a camera from the list, you are really selecting the CoC that will be used in the DoF calulation.) Many photographers prefer to choose a value that is somewhat smaller than commonly specified; this has the effect of suggesting a smaller f/stop and larger DoF. Here's where this app shines: it uses scroll wheels to enter data. This makes it incredibly easy to fine tune the DoF values when making compositional changes to focal length using a zoom lens. And in addition to the common list of camera models, you can simply select the CoC you want to use. It also support two camera model (or CoC settings) if you have cameras with different sensors. Whether you decide to use a Camera Model or select a CoC, this app is fast to use and easy to read DoF values. The fact that it's free is amazing!

Easy to use and does what it is supposed to do. Even offers no cost updates for new cameras. No attempt to sell me anything else. Nice.

I tried some other DoF apps but none compare to the slick interface and ease of use of this one. Well worth the couple bucks.

the app to use and understand...a great help when trying to achieve maximum dof
