Fish eye lens is wide-angle lens that captures extremely extensive globe like images. Initially, the fisheye lens was prepared for astronomy and meteorology. They were in fact known as whole-sky lenses. Fisheye lenses got popularity because of the distinctive hazy pictures they formed. Fish eye lens pictures were utilized when shooting extensive landscapes.
The fisheye lenses focal lengths depend on the film format. Fisheye lenses contain short focal length below 17mm for a 35mm camera. Ordinary fish eye focal-lengths for a 35 mm camera are 6mm to 8mm (gives a circular image) and 15mm or 16mm (gives a full-frame, curvilinear image). The ultra wide angle view gives purposeful image distortion in which curved or bent strokes might seem to be straight and straight strokes might seem to be bent or curved. Fisheye lenses make objects seem to promptly contract in magnitude as the distance from the camera amplifies and the objects close to the camera seem distant apart. With fish eye lens, every time focusing might not be compulsory as the depth of field often enlarges from inches in front of the lens to infinity.
With Nikon fisheye lens and also with other brand name lenses there are two types of fisheye lenses:
The circular: (One of the first to be developed).
The full frame.
Circular Lens
An Olympus fisheye lens when used with the circular lens it will works in 180 degree hemisphere. These lenses usually have 8mm focal length. It shows the picture within the film frame as a circle. The Peleng 3.5/8 mm fisheye lens is one of the few circular fisheye lenses that are currently available in the market but it stand out because of its price. The price depends upon the buying place of Peleng lens. These lenses are easily available in market.
Full Frame Lens
With the help of full frame fisheye lens for instance the Sigma fisheye lens, the Swann fish eye lens or the Canon fisheye lens the original circle has been extended to coat the complete 35mm film frame. From this it is concluded that the picture angle for these lenses only measures 180 degrees i.e. from corner to corner. These lenses normally have a 15 or 16mm focal length. The Nikon fisheye lens, the first full-frame fisheye lens, produced in bulk was the 16mm lens and introduced in 1960. This lens is generally the one which is used by the majority of photographers.
Fish Eye Lens Accessibility
There are many mm fisheye lenses like 27mm fisheye lenses, the 58mm fish eye lens and the 65mm fisheye lens. They are available on different online website including eBay, as third party sourced lenses (mostly used lenses) or other auction and manufacture’s (company) web sites.
Fisheye Lens Choices
Sigma and Canon both create 15mm f2.8 auto focus fisheye lenses for Canon EOS bodies. The Canon Lenses and the Sigma lenses are available in different price range. A Nikon mount version is also available.
Circular fisheye lenses are harder to acquire because Canon does not build one in an EOS mount. However, Sigma does create 8mm f4 circular fisheye lens in EOS mount for about $580. There is also complete manual version made the Peleng 8mm f3.5 in Ukraine. Again the top place to search for one is on eBay.
Fisheye lenses have different prices. These lenses are available in different sizes, styles, shapes, auto / manual focus models and along with different types of accessories.
