Telephoto lenses are a great way to capture images of things that are far away. They are ideal for photographing things like sporting events, landscapes, and nighttime skyscapes. Oftentimes, a telephoto lens can also give a photographer the ability to take shots that would be unattainable without the use of a tripod.
When you are capturing a scene that is far away, you need to be able to keep your focus on the subject and not on the background. The longer the focal length of a telephoto lens, the more magnification you will get. Longer focal lengths can also allow you to isolate the subject and reduce blur caused by camera shake. This makes it a good option for capturing candid moments, and it can also help you avoid blurring the background, as well.
Telephoto lenses can also provide a unique perspective, allowing you to see the scale of a distant object in a photo. A telephoto lens can also be used to create an artistic image by focusing on an unusual element in the foreground. For instance, you can take a telephoto lens to a savannah or a volcano to capture a unique view.
Compared to other lenses, telephotos have a large aperture and can produce a shallow depth of field. Because of this, a telephoto will create a clear image of a distant object, as well as a flattering image of the subject. Having a shallow depth of field is important to prevent the background from becoming distracting. Some manufacturers have added optical stabilizers to their telephoto lenses, which will help you hold the camera steady during handheld telephoto shooting. Optical stabilizers are often paired with panning and static modes, which will help you achieve the right panning angle for the desired effect.
Another telephoto-specific feature is a refracting lens, which bends light before it hits the sensor, straightening it out. A refracting lens can make objects appear smaller than they actually are, and this can be an advantage for a wide variety of photographic applications. Similarly, a curved mirror lens can create a magnifying effect.
Depending on the lens you buy, you can expect it to be heavy and have many pieces of glass inside. Many telephotos will include a tripod collar to help support the weight of the lens.
If you are looking for a good telephoto for your SLR or mirrorless Z-series camera, you should consider the Canon EF-S 55-250mm f/4-5.6 IS STM. This telephoto zoom features a fast Nano USM autofocus system, as well as five ED elements and high-tech coatings. In addition, the lens features a compact design that is suitable for small cameras, as well as an in-barrel information screen.
Among telephoto lenses, the Tamron 70-300mm f/4.5-6.3 Di III RXD is a fairly priced option that offers excellent image quality for the price. Its short telephoto and super-telephoto lengths make it a suitable tool for Sony A6000 users. However, it is not the sharpest of the bunch.
