The smc Pentax-DA 10-17mm f/3.5-4.5 ED (IF) Fish-Eye lens is a fisheye zoom lens for the Pentax K-mount.It offers an up to 180 degree view, and allows quick shift focus (Pentax's term for giving the photographer the ability to manually focus the lens even when the camera is in autofocus mode without damaging the lens or camera).
Fisheye is a revision-control browser [1] and search engine owned by Atlassian, Inc. Although Fisheye is a commercial product, it is freely available to open source projects and non-profit institutions. [2] In addition to the advanced search [3] and diff capabilities, [4] it provides:
The OSLO software is used by scientists and engineers to design lenses, reflectors, optical instruments, laser collimators, and illumination systems. It is also used for simulation and analysis of optical systems using both geometrical and physical optics. In addition to optical design and analysis, OSLO provides a complete technical software ...
This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.
In a circular fisheye lens, the image circle is inscribed in the film or sensor area; in a diagonal ("full-frame") fisheye lens, the image circle is circumscribed around the film or sensor area. This implies that using a fisheye lens for a different format than it was intended for is easy (as opposed to a rectilinear lens), and may change its ...

Some fisheye lenses use a stereographic projection to capture a wide-angle view. [26] Compared to more traditional fisheye lenses which use an equal-area projection, areas close to the edge retain their shape, and straight lines are less curved. However, stereographic fisheye lenses are typically more expensive to manufacture. [27]
