Camera lens
A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.

Field flattener lens
Field flattener lens is a type of lens used in modern binocular designs (e.g. Canon 10 x 42 L IS WP, 18 x 50 IS All Weather and Swarovski EL 8.5 x 42, EL 10 x 42) and in astronomic telescopes.

Film plane
A film plane is the area inside any camera or image taking device with a lens and film or digital sensor upon which the lens creates the focused image.

Flat-field correction
The brightness variation due to vignetting, as shown here, can be corrected by selectively brightening the perimeter of the image. Flat-field correction is a technique used to improve quality in digital imaging.

Hyperfocal distance
In optics and photography, hyperfocal distance is a distance beyond which all objects can be brought into an "acceptable" focus.

Joseph Petzval
Joseph Petzval (6 January 1807 – 19 September 1891) was a mathematician, inventor, and physicist best known for his work in optics.

Optical aberration
Aberration in optics refers to a defect in a lens such that light is not focused to a point, but is spread out over some region of space, and hence an image formed by a lens with aberration is blurred or distorted, with the nature of the distortion depending on the type of aberration.

Petzval lens
The Petzval objective or Petzval lens, is the first photographic portrait objective lens (160mm focal length) in the history of photography; It was developed by the German-Hungarian mathematics professor Josef Maximilian Petzval in 1840 in Vienna, with technical advice provided by, the Voigtländer company went on to build the first Petzval lens in 1840 on behalf of Petzval, and whereupon it became known throughout Europe.
