The fixed-focus lens is sharp from three feet to infinity.

For 35 mm cameras, some superwide fixed-focus lenses have been made.

The device has a fixed-focus lens, a 2X digital zoom and a timer.

As a result, many miniature cameras make do with fixed-focus lenses and simply forget about zooming.

Like the low-cost eight-millimeter movie cameras of old, the Key019 has a fixed-focus lens.

Digital cameras often have fixed-focus lenses not unlike those found on cheap disposable film models.

The original iPhone launched with a fixed-focus lens and a paltry (even for 2007) 2 megapixel sensor.

Model XA1 used a fixed-focus lens.

Most use fixed-focus lenses.

It has a fixed-focus lens, eye level optical viewfinder and an LCD screen on the back.

A photographic lens for which the focus is not adjustable is called a fixed-focus lens or sometimes focus-free.

There is also the fully electronic entry-level model, the EC, which has a very different internal design and has a fixed-focus lens.

The trade-off is the optics: the fixed-focus lens is limited in range and the zoom is digital only.

It was a very simple box camera with a fixed-focus lens and single shutter speed, which along with its relatively low price appealed to the average consumer.

Fixed-focus lens with Extended Depth of Field (EDoF), marketed as "full focus"

Rather than having a method of determining the correct focusing distance and setting the lens to that focal point, a fixed-focus lens relies on sufficient depth of field to produce acceptably sharp images.

Fixed-focus lenses are unable to produce sharp close-ups, or images of objects that are only a fraction of the hyperfocal distance from the camera which, depending on factors including the size of the camera, may be within 2.4 - 3.7 meters (8-12 feet).

Especially suitable are fixed-focus lenses for low resolution CCD cameras as found in webcams, surveillance cameras and camera phones, because the low resolution of the image sensor allows a loose focusing on the CCD without noticeable loss of image quality.

The optic is a 1-group lens, which is based on a shiftable fixed-focus lens: similar to the highly regarded prime lenses in most Zeiss Planar or Tessar optics, focus is achieved by varying the distance to the image sensor (unit focusing lens).

Since fixed-focus lenses require no input from the operator, they are suitable for use in cameras designed to be inexpensive, or to operate without electrical power as in disposable cameras, or in low-end 35 mm film point and shoot cameras, or in cameras featuring simple operation.
