Photographing with 70-210mm Camera Lenses

In situations where you can't get as close to your subject as you'd like, a long focal length camera lens can come in very handy. Equipped with autofocus (AF) and image stabilization technology, modern telephoto zoom camera lenses make easy work of capturing crisp and sharp images, even at the longest end of the focal length. Whether you're heading out on safari to document wild animals or capturing all the action of sporting events from the boundary, an AF 70-210mm zoom could be a wise choice.

What Are the Advantages of a Telephoto Lens?

A telephoto lens refers to one that is generally 100mm or longer, with some telephoto zooms spanning from 70mm to 210mm in focal length. They offer much greater reach for photographing subjects that are at a distance and the opportunity to capture up-close details that aren't visible to the human eye.

• The most obvious advantage of a telephoto zoom lens is its ability to make a distant subject appear much closer than it actually is. They can be really useful for wildlife photography in situations where trying to get close to the animal may cause it to run away, as well as sporting photography where a boundary may restrict you.
• You can also use telephoto zoom lenses with wide maximum apertures to capture beautiful portraits with a blurred background or bokeh effect that clearly separates the subject from what's behind.
• There are some instances where you may want to completely fill the frame with your subject, rather than having it as part of a bigger picture. Long focal length zooms can achieve this while capturing all the little details that may otherwise be lost.

What Should You Look for When Buying a 70-210mm Lens?

A variable focal length telephoto camera lens is a good choice when you want versatility, with the ability to rapidly change between focal lengths without having to change lenses. You can find both big-brand camera manufacturer lenses that are compatible with their camera bodies, as well as third-party models, such as the Sigma 70-210mm.

• Make sure the 70-210mm you are considering is compatible with your camera body's make and model. This should be clearly indicated in the product description or on the packaging.
• It's important to keep in mind that 70-210mm can be quite heavy and bulky to carry around, so check its weight and whether it suits the practicalities of your photographic style.
• Telephoto zooms are also more prone to showing signs of blurriness due to camera shake when handheld, so look for models that have image stabilization technology or opt to use your lens with a tripod for greater stability.
