Available lens models

The polynomial optics lens system operates on real lens data, sourced from lens patents. Since the lenses are pre-computed to make raytracing through many glass elements much faster, all lenses are prime lenses. For most lenses however, we've supplied multiple focal lengths - like it would be done for real cinema line lenses.

Kodak Petzval

Kodak's take on the classical Petzval design. Features a heavy amount of optical vignetting, resulting in swirly bokeh which helps emphasise the subject in focus.

Year: 1948

Available focal lengths: 150 105 85 65 75 58

Lens patent number: US2500046A

Minimum f-stop: 2.2

Asahi Takumar

The Asahi Takumar (Pentax) is based on the Zeiss Biotar.

Year: 1969

Available focal lengths: 45 50 65 75 58 85

Lens patent number: US3451745

Minimum f-stop: 1.24

Angenieux Double Gauss

A six element objective with a huge aperture. Due to optical vignetting in the lens, it creates very swirly bokeh.

Year: 1953

Available focal lengths: 49 85 105 55

Lens patent number: US2701982

Minimum f-stop: 1.11

Unknown Petzval

The Petzval lens is the first photographic portrait objective lens in the history of photography. It was developed by the mathematics professor Josef Maximilian Petzval in 1840. It was the first mathematically calculated objective in the history of photography. The lens was able to let 22 times more light in than any other design at the time. This enabled photographers to for the first time take portraits with exposure times of less than a minute.

Year: 1900

Available focal lengths: 85 100 75 65

Lens patent number: None

Minimum f-stop: 3.4

Cooke Speed Panchro

Cooke Series O f/2.0 OPIC lens, Horace W. Lee designed. This original f/2.0 OPIC design became the now-legendary uncoated Cooke Speed Panchros. Studios jumped up the new Cooke f/2.0 (T2.3) lenses, due to which they appear in almost every film in the early hollywood era.

Year: 1920

Available focal lengths: 40 75 100 50

Lens patent number: GB157040A

Minimum f-stop: 2.0

Zeiss Biotar

The Biotar was developed by the famous lens designer Dr. Willy Walter Merté for Carl Zeiss, it is a six element lens with asymmetrical outer elements, a variant of the Double Gauss design for higher performance and increased field correction and speed. Virtually all of today’s fast lenses with a medium field angle (50-100mm focal length on 35mm cameras) are Double Gauss designs, like the Biotar. These Double Gauss lenses attempted to improve on the Planar design from 1896 by abandoning the strict symmetry approach for the radii of curvature of the surfaces and the refractive indices of the glass materials and therefore achieved additional correction parameters. The famed Helios 44-2 lenses are very close clones of the Biotar.

Year: 1927

Available focal lengths: 65 58 85 45

Lens patent number: DE485798C

Minimum f-stop: 1.4

Nikon Unknown

Modern f/1.25 design by Nikon.

Year: 2014

Available focal lengths: 65 40 50

Lens patent number: US8721094

Minimum f-stop: 1.23

Asahi Takumar

SMC Takumar f2.0. If you've ever had an old pentax in your hands, it probably had one of these lenses screwed on.

Year: 1970

Available focal lengths: 28 50 35

Lens patent number: US3506336

Minimum f-stop: 1.96

Minolta Fisheye

High speed fisheye lens capable of compensating for lateral chromatic aberration, field curvature and astigmatism while providing an aperture ratio of f/2.8. 180 degree field of view.

Year: 1978

Available focal lengths: 16 22 28

Lens patent number: US4256373

Minimum f-stop: 2.66

Meyer-optik-goerlitz Primoplan

The Primoplan 58 was developed by the brilliant Meyer-Optik designer Paul Schäfter 80 years ago. Its light intensity of 1:1.9, which was considered extremely high back then, made the Primoplan 58 f1.9 one of the most exciting lenses of its time. It features lots of optical vignetting, making for very swirly bokeh. A recent re-release also included the 75mm.

Year: 1936

Available focal lengths: 58 75

Lens patent number: DE1387593

Minimum f-stop: 1.47

Nikon Retrofocus Wideangle

A 7 element retrofocus-type wide angle lens with a relative aperture of F/2.8, an angle of field of 75° and a back focus of more than 1.3 times the focallength.

Year: 1971

Available focal lengths: 28 35

Lens patent number: US3583791

Minimum f-stop: 2.75

Canon Unknown

At the time of introduction, this was the highest aperture 35mm lens. In April 1956, Canon introduced a number of new lenses to coincide with the important launch of the Canon VT. The new Canon 35mm f1.8 was one of these.

Year: 1956

Available focal lengths: 35 52

Lens patent number: US2854890

Minimum f-stop: 1.84

Canon Retrofocus Wideangle

A compact retrofocus-type wide angle lens which is well compensated for various aberrations considering its remarkably large field of view (114 degrees).

Year: 1982

Available focal lengths: 22

Lens patent number: US4310222

Minimum f-stop: 2.65
