Two suggestions if you are going to add features. Installed the Mac version. Hi Jeff Congratulations on your Lens Lab app, which is really well designed and great to use. If I put a 50mm f1.
So then I am left wondering, what would the new distance be so that I can determine the new DOF for equivalent framing? Thanks for your comments and question. Thanks again! Hi peter, are you talking about the Mac version?

Here is a quick review for beginners. The first variable is aperture, the amount of light passed by the lens, measured in f-stops. The narrower the aperture, the greater the depth of field. Aperture and f-stops can themselves be confusing for beginners, since they're inversely related. The distance to your subject is the second variable.

The closer your subject, the less the depth of field which is why close-up macro shots may have a depth of field measured in fractions of an inch. Finally, consider the focal length of the lens—the longer the lens, the less depth of field. So far, so good. But the interplay of variables can lead to trouble for the unsuspecting.

But that low f-stop will result in a shallow depth of field - leaving some subjects out of focus, unless you compensate. Depth of field calculators help beginners and pros alike quickly sort out these details to ensure the desired results. Calculations and adjustments are made on a single screen which—while easy to read—assumes you possess a good grounding in the subject. You adjust aperture and distance variables via sliders, while a simple panel details the total depth of field, the distance of the near and far limits of the zone of focus, and the distance it extends in front of and behind the subject.
You can also specify different sheet film sizes and cinematography settings, along with custom descriptions. Some may question the value of a paid app like this, seeing as there are many free options available. The difference is in how well the app works, and how easy it is to extract the required information.
This app excels in both areas. Huge range of input options High degree of accuracy with calculations Useful diffraction limit warning for small apertures Input fields are clear and easy to use.
