Hi,
I'm new to this so please forgive me if this sounds like a really dumb question
I have a question regarding using the DOF calculator for a specific lens.... I am curious about the distance value and how it is measured.
Is this measurement made from the front of the lens or.... is it made from the cameras sensor plane?
Thanks!
Jay

Neither, actually. It's the distance from the lense's focal plane, which should be somewhere between the front and the back lenses. Which is to say, you can't measure the distance with extreme precision because you don't know the focal plane's position, but such precision is not necessary anyway. Simply pick a point on the lense's body and measure from it.
