* [[Apochromat]] (apo) lenses have added correction for [[chromatic aberration]].
* [[Process lens]]es have extreme correction for aberrations of geometry ([[pincushion distortion]], [[barrel distortion]]) and are generally intended for use at a specific distance and at small aperture.
* Enlarger lenses are made to be used with [[photographic enlarger]]s (specialised projectors), rather than cameras.
* Lenses for [[aerial photography]].
* [[Tilt–shift photography|Shift len]]s allow the lens to be raised or lowered relative to the film of sensor plane to correct or exaggerate perspective distortion.
* [[Fisheye lens]]es: extreme wide-angle lenses with an angle of view of up to 180 degrees or more, with very noticeable (and intended) distortion.
* [[Stereoscopy|Stereoscopic lenses]], to produce pairs of photographs which give a 3-dimensional effect when viewed with an appropriate viewer.
* [[Soft focus|Soft-focus]] lenses which give a soft, but not out-of-focus, image and have an imperfection-removing effect popular among portrait and fashion photographers.
* [[Infrared photography|Infrared lenses]]
* [[Ultraviolet photography|Ultraviolet lenses]]
* [[Swivel lens]]es rotate while attached to a camera body to give unique perspectives and camera angles.
* Shift lenses and tilt/shift lenses (collectively [[perspective control lens]]es) allow special control of [[perspective (visual)|perspective]] on [[Single-lens reflex|SLR]] cameras by mimicking [[View camera#Movements|view camera movements]].
* [[telecentric lens]]es (or orthographic lenses) make any object appear as the same size regardless of their distance from the lens.
