The fisheye term coined by American physicist Robert Wood W as well as its inventor in 1906. The designation is based on how the sight of fish in view of their environment, which is an ultra-wide visual of hemispherical bottom water. The first fisheye lens used in practice in 1920, which is used in meteorology to study cloud formation. Perspective fisheye lens is usually between 100 and 180 degrees, while the focal length depending on the film format.
Fisheye lens into mass production to photography in the early 1960s and is commonly used to generate a unique image and distorted image. In the 35 mm film format, typical fisheye lens focal length is between 8 mm and 10 mm for the circles, and 15-16 mm for full-frame. For digital cameras using smaller electronic imagers such as 1/4" and 1/3", the focal length of "miniature" fisheye lenses can be as close as 1 to 2mm.
When you replace the normal lens with a wide angle lens, then you do not have to backtrack too much, then the whole child in the classroom has entered the frame. Then when you replace the lens with a wide angle fisheye lens, you do not even need to retreat at all, it's just that the results of the drawing will be visible convex, like you see a shadow on a spoon (it felt maybe it was not as extreme, but it does look like it).
Fisheye lens has been applied extensively, particularly for research, tourism, adventure and others. But the fisheye lens is less appropriate when used for shooting models, except when it expects dramatization environment (meaning not too focused on the model). Combined with Macros in it, can be applied for macro shooting more dramatic than in the ordinary macro lens.
