Lensbaby 12mm f/4 Fisheye
Auxiliary Optic for Composer
Make your Lensbaby Composer a fisheye lens by using the Fisheye Optic, a member of the Lensbaby's Optic Swap Structure. This Lensbaby Fisheye Optic is a 12mm ultra-wide focal length lens which acquires an fisheye view from as close as one inch away to infinity.
The Fisheye Optic was engineered to be mounted with the Composer, however it can also work with the Muse by purchasing a special adapter. The Fisheye Optic should not be mounted with the Lensbaby Control Freak.
The Fisheye Optic encompasses an interchangeable aperture disk system, with available aperture settings which start from f/4 and go to f/22. The edges of the Lensbaby Fisheye photos are soft at f/4. At f/22 your whole photo is quite sharp. Stopping down using smaller aperture openings will improve edge sharpness.
Because of the extremely wide viewing angle, photographers using full frame cameras will typically notice a black circle surrounding practically their whole image, while photographers using APS-sized sensors will notice black at all corners of their pictures. These black corners are normal for standard circular fisheye lenses.
Additionally, the Fisheye Optic encompasses unique lens flaring which turns the edges that are typically black to glowing color when bright light sources appear in the photo. This lens flare is especially apparent when photographing using a full frame 35mm camera.
The Fisheye Optic contains a much more flat focus field than prior Lensbaby Optics. The pictures produced by this Fisheye Optic are crisp all through the image using darker apertures.
At more brilliant apertures some softening occurs along the edges although not at the crisp focus Sweet Spot and spectacular blur that are the Plastic Optics, Single Glass, and Double Glass trademarks. In place of bending this lens, users will most often point their Lensbaby in a straight forward manner to produce a classic fisheye appearance.
A fisheye lens captures a wide, hemispherical image on the extreme side. Initially developed for meteorology use in studying formations of clouds and labeled as "whole-sky lenses", these fisheye lenses fast became popular for all around photography because of the unique, distorted appearance of photographs they captured . They are typically used by photographers acquiring broad landscapes that suggest the earth's curve. Hemispherical photography is also used for an array scientific purposes in studying the geometry of plant canopy and for calculating solar radiation near the ground.
The first fisheye lenses which were created were "circular fisheyes" type lenses which capture a 180° hemisphere which shows as being a circle within a film or sensor frame. A few circular fisheyes can be acquired in orthographic projection versions for scientific applications. These lenses feature a 180° vertical viewing angle, while the diagonal and horizontal viewing angle are also 180°. The typical circular fisheye lens covers a lesser image circle as compared to rectilinear lenses, allowing the frame corners to be completely dark.
