I watched the lesson where you showed the DOF Master app for your phone to calculate DOF.  I bought the app but am unsure which  focal length to enter.  I have the D7000 which is DX and I just purchased the 50mm 1.4D lens, which I believe is FX lens.  Should I enter 50mm or should I enter 75mm since that is what my camera will see?

 

Thanks for your tutorials.  I am learning a lot.

You enter the camera model, you use and focal lengths as it is. So for 50mm 1.4D lens, you enter 50mm. It doesn’t matter if lens work with FX or no. What matters is the camera you use.
