Depth-of-field adapter

The use of adapters has decreased largely due to the video function available on newer DSLR cameras.

DOF adapters have been developed for use with smartphones, allowing DSLR lenses to be used with phone cameras.

The lens attached to the adapter now takes the job of the camcorder's focusing and aperture mechanisms.

Static (non-moving) adapters suffer greater image degradation from low-light situations because the texture on the focusing screen becomes more noticeable.

As a result, the camcorder also picks up the pits, dimples and/or specks in the material that give it its translucent properties.

To help address this issue while filming, an external monitor such as a small LCD screen may be mounted upside down to view the image in its correct orientation.

This avoids the burden of needing an external LCD monitor, but at the cost of additional light loss.

The price of a DOF adapter ranges from tens of thousands of US dollars for a professional solution to less than a hundred by using parts available from a local hardware store.
