For example, a 35 mm lens mounted on a full-frame Canon EOS 5D provides a slightly wide-angle view, while the same lens mounted on an APS-C Canon EOS 400D provides a "normal" or slightly telephoto view. In order to more easily compare lens–camera pairs, it is common to use their 35 mm equivalent focal length.

Zoom lenses cover a range of focal lengths by utilising movable elements ...
Canon PowerShot N100, has also rear-facing lens as smartphone, but front and rear lenses both together will take photo/video when the shutter is pressed and the rear lens image will appear in the corner of the big image from front lens as picture-in-picture, so the camera is called as a 'Story Camera' [5]

The fast f /2 aperture makes the lens ideal for both of these applications. Among Canon photographers, the lens is highly regarded for its sharpness, contrast, and color ...
When used on a digital EOS body with a field of view compensation factor of 1.3x, such as the Canon EOS-1D Mark IV, it provides a narrow field of view, equivalent to a 390 mm lens mounted on a 35mm frame body. With a 1.6x body such as the Canon EOS 650D, it provides a narrower field of view, equivalent to a 480 mm lens mounted on a 35mm frame body.
A teleconverter (sometimes called tele extender) is a secondary lens mounted between a camera and a photographic lens which enlarges the central part of an image obtained by the lens. For example, a 2× teleconverter for a 35 mm camera enlarges the central 12×18 mm part of an image to the size of 24×36 mm in the standard 35 mm film format .
