Everything You Need to Know About Canon Fisheye Camera Lenses

A camera lens can provide you with the means of capturing different kinds of photos, from landscapes to portraits. A fisheye lens helps to deliver a wide-angle image with a field of vision that extends to up to 180 degrees, which makes for a picture that has some distortion at the edges. These lenses are made by a wide array of manufacturers that includes Nikon, Canon, Sigma, Tamron, and Vivitar.

How do you select a fisheye camera lens?
  • Select a mount: Some of the mounts available for these lenses include EF, EOS, IS, and F mounts.
  • Select a focal length: The focal lengths available with these devices range from 3.4 millimeters to 24 millimeters.
  • Select a type of camera: These lenses can be used with camcorders, SLR cameras, and digital SLR cameras.
  • Select a maximum aperture: The maximum aperture for fisheye lenses can vary from f/1.2 to f/8.
How do you keep a fisheye camera lens clean?

The first aspect of cleaning a camera lens is to make sure not to do it too often because you want to avoid removing any of the coatings on the lens. To clean off the accumulated dust, consider using a dust blower or small microfiber cloth, the latter of which will also assist in removing any smudges or fingerprints. If any substances remain on the lens after the initial cleaning, you could consider using a lens-cleaning fluid and a cleaning cloth to remove the substances.

What are the focal lengths available with a fisheye lens?

When you are selecting a fisheye lens, it can be equipped with a range of different focal lengths. These lengths are available as either fixed amounts or as a zoom length; the zoom option provides a range of lengths, such as 20 to 200 millimeters. These lengths are always listed in millimeters. This number refers to the distance between the very center of the lens and its focus. The higher the number, the more magnification the lens will have. The length amounts that are usually available with fisheye lenses depends on the type of camera the lens is being used with. For cameras with 35-millimeter film, fisheye lenses will have a length of 8 to 10 millimeters. Full-frame lenses come with slightly longer lengths of 15 to 16 millimeters. See the manufacturer site for details.

What are the different focus types with these lenses?

There are three main types of focuses with this camera lens:

  • Auto: This is a type of system that automatically focuses the image without requiring you to do so before taking a picture. This system makes use of a small motor in the camera that hones in on a specific object within the image.
  • Manual: This is a type of system that provides you with manual operation of the focus settings. Most lenses that come with manual focusing will be equipped with a focus ring towards the base of the lens.
  • Auto/manual: This is a type of system that offers both auto and manual focusing controls. Such camera types as DSLR cameras typically come equipped with both auto and manual focus controls.
