As the focus distance changes, so do the depth of field. When shooting landscapes, it is often necessary to be clear from far and near, in other words, to maximize the depth of field.

In addition to the amount of light, aperture also controls what is called “depth of field.” It’s the amount that’s in focus in a scene from front to back.

The two primary designs for giving patients a wider range of vision without glasses are multifocal IOLs and extended depth of focus (EDOF) IOLs, each having their own benefits and compromises. 1.

Inspired by the dual-focus visual system of a 500-million-year-old trilobite, researchers have created and tested a light field camera with the greatest depth of field ever demonstrated ...

Fixed parallax riflescopes tend to have a much deeper depth of focus. For example, I have a 4.5-14X Leupold VX-3 riflescope that does not have a parallax adjustment.

Apple is making Cinematic mode video capture available beyond its Camera app on the iPhone. In a WWDC 2025 session earlier this month, ...
