Simple DoF Calculator

This is a fantastic app; it is well designed and easy to use. I love that you can set and keep up to four cameras with their own different settings, really handy if you have more that one, otherwise you would have to scroll through hundreds of them in its database to choose a different one. The last used settings are retained even if you quit the app. As per how accurate it is, I haven’t done any thorough testing yet, but it seems to be pretty good.<br/><br/>One request: please add a setting for optionally displaying 1/3, 1/2, or full f-stops - less scrolling is always better, especially if you don’t have to. Thank you.

Much better than using a web based calculator, and way better than other abandoned DOF calculators in the App Store. Wish it was possible to add custom cameras (or at least rename the camera choices to match your kit), and the text in the &quot;road&quot; could be larger and easier to read in a hurry, but otherwise a perfect app.

Easy to use and accurate. There are more complex ones out there, but they give the same answer, only to more decimal places (try setting your focus to 19.37 feet, I challenge you!). Definitely my go-to tool.

Very clean user interface, excellent selection of cameras, but doesn’t allow user to adjust circle of confusion diameter or reproduction ratio. What’s worse, I can’t even find their assumptions about these parameters.<br/>Excellent for beginners, not so much for pros.

Was a very good app, with both graphical and numeric feedback. Depiction of DoF is excellent. But lack of newer camera inclusion and silence from developers suggests moving on. A good implementation that’s not keeping up.

The new cameras are not included. Its time to update.

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.<br/><br/>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. <br/><br/>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.<br/><br/>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!

This has been my go to app for DoF but I recently bought an APS-C camera and asked the developer to include it in supported brands some time ago. A reply, either way, would have resulted in 5 rather than 4 stars.
