A Quick Look at Telephoto Camera Lenses for Canon

When you are going on vacation to a national park or a big city, having a telephoto lens on hand will allow you to zoom in on your subjects. These lenses are compatible with a wide array of mounts and can be used in combination with both digital and film cameras. They come in a range of focal lengths, starting at 3.4mm and exceeding 1,000mm.

How does a telephoto lens work?

This is a type of lens that comes with a long focal length, which helps to produce an image that is magnified and has a narrow field of view. Since these lenses are equipped with long focal lengths, the size of the lens itself is usually long as well. These lenses typically come with focal amounts of 60mm or longer. Some models are zoom lenses, while others have a fixed focal amount. This type of lens allows subjects that are far away to appear closer to the lens.

What camera types can these lenses work with?

Several cameras work with telephoto lenses, including:

  • Digital single-lens reflex: This is a type of digital camera that comes with an array of both automatic and manual settings. These devices come with interchangeable lenses and have digital sensors. They also use memory cards for photo and video storage.
  • Rangefinder: This is a type of camera that comes with a built-in rangefinder that can assist you in determining the exact distance from the lens to the subject of your photo, which can help you identify how much the lens should be focused.
  • Camcorder: This is a device that is designed to capture videos, which can be done in a variety of standard-definition and high-definition resolutions.
  • Mirrorless: This is a device that comes without a mirror system and is outfitted with a digital sensor as well as interchangeable lenses. These models come in a compact form due to the absence of mirrors within the body.
What does the maximum aperture of a lens refer to?

The aperture of a lens refers to the amount of light that the shutter lets in when you take a photo. The aperture of a lens is always displayed with an f-stop followed by a number, such as f-8 or f-3.2. Maximum apertures allow in a substantial amount of light, while minimum apertures let in only a small amount of light. A maximum aperture is commonly associated with a smaller number, such as f-1.2. A minimum aperture is represented by a larger number, like f-18 or f-22. These telephoto lenses come with maximum aperture ranges that extend from f-1.2 to f-16.
