Fixed focus can be a beneath big-ticket another to autofocus, which requires electronics, affective parts, and power. Since fixed-focus lenses crave no ascribe from the operator, they are acceptable for use in cameras advised to be inexpensive, or to accomplish after electrical ability as in disposable cameras, or in low-end 35 mm blur point and shoot cameras, or in cameras featuring simple operation. These are usually wide-angle lenses with anchored aperture, and cameras with these lenses about use a viewfinder for composition.
Especially acceptable are fixed-focus lenses for low resolution CCD cameras as begin in webcams, surveillance cameras and camera phones, because the low resolution of the detector allows a apart absorption on the CCD after apparent accident of angel quality. Therefore the amphitheater of abashing gets bigger and hyperfocal ambit smaller.
Special-purpose cameras such as the Agiflite1 are acclimated for situations like aeriform photography from aircraft. Because the arena is far from the camera, focus acclimation is not necessary. For 35 mm cameras, some superwide fixed-focus lenses accept been made.2
