Long-focus lenses with a shorter effective focal length than the lens’ physical length are known as telephoto lenses. Your SLR or DSLR camera, such as those made by Canon, Nikon, and other top brands, will have a telephoto lens attached to the camera body. Even some smartphone cameras can accommodate telephoto lenses.
What Is a Telephoto Lens Used For?
A telephoto lens deceives the eye into thinking a topic is closer than it actually is. This may be the best option for photographers who can’t get near to their subjects owing to physical restrictions or safety concerns. These lenses are exceptional at distinguishing foreground and background focal points and also serve an artistic function.
What Kinds of Telephoto Lenses Are There?
Most telephoto lenses fall into the medium and ultra telephoto categories, with focal lengths between 70 and 200mm. Such lenses enable full frame photography over a wide range of shutter speeds and f-stop values, from quick action shots in broad daylight to nighttime images taken at the lens’ maximum aperture. These lenses can either slightly or substantially alter your camera’s field of view. Within this range, some well-liked telephoto lenses are as follows:
Any focal length that falls within the specified range is reachable with 70-200mm lenses. These are excellent for portrait photography since they have a crisp subject and a nice background bokeh blur. In the meanwhile, these lenses are useful for long-distance event photographs, such as at a wedding or athletic event, when they are at the outer limits of their range.
- Zoom lenses with focal lengths of 100–400 mm are also available, and they extend the capabilities of the 70–200 mm lens. The lengthy focal length and useful zooming of these lenses are appreciated by sports and wildlife photographers.
- The small depth of focus of 85mm prime lenses makes them ideal for portrait photography with foreground subjects that are crisp and backgrounds that are blurry. The “portrait mode” that many modern digital cameras and cell phones provide imitates the look of an 85mm prime lens.
- Even at larger distances, 135mm prime lenses offer a shallow depth of field similar to 85mm prime lenses. They are used for photography that is more creatively experimental, such as portraits, weddings, and events.
Tips for Using a Telephoto Lens.
There are three excellent ways to utilize your telephoto lens to its full potential.
1. To accurately depict scale in your photos, use a telephoto lens. In contrast to a wide-angle lens, which can change the dimensional perspective of a scene, a correctly employed telephoto lens can show all of the elements in a scene in their true sizes.
2. For a heightened depth of field, use lengthy focal lengths; for a balanced sharpness between the foreground and background of your picture, use shorter lengths.
3. Watch out for camera shake. Telephoto lenses amplify the finest and worst aspects of your photography in equal measure. So be careful that a telephoto lens doesn’t magnify your shaky photography approach. Prior to experimenting with telephoto technologies, perfect your technique.
What Distinguishes a Zoom Lens from a Telephoto Lens?
The terms telephoto lens and zoom lens are interchangeable among some amateur photographers. These two lenses aren’t exactly the same, in reality.
A telephoto lens has a long reach, which generally entails a focal length of 60mm or greater, but it is not required to be able to switch between different focal lengths.
The ability to switch between several focal lengths is what distinguishes a zoom lens, although some zoom lenses don’t magnify sufficiently to be referred to as “telephoto.
Having a telephoto zoom lens, which changes focal lengths, or a telephoto prime lens, which has a fixed focal length, is what this practically means.
Distinguishes between a Wide Angle Lens from a Telephoto Lens?
- Wide-angle and telephoto lenses are not interchangeable.
- The focus length is extended with a telephoto lens. It’s most frequently employed to depict distant things with a level of precision and perspective that was previously only attainable with close-up photography.
- The horizontal range of a camera shot is increased by using a wide angle lens. On the one hand, this can help an image resemble what we see when we look at the environment in person.
- However, wide-angle lenses frequently alter perspective in a shot. Wide angle lenses typically have a greater depth of field, which makes them inferior to telephoto lenses for portrait photography and other situations when you want only the subject in perfect focus.
