Photographing with 28-70mm Camera Lenses

A common element in most entry-level digital single-lens reflex (DSLR) camera kits is a variable focal length lens, such as a 28-70mm, which many photographers use for its versatility and ease of use. It offers a focal range suitable for a wide variety of different photographic settings, so you don't need to keep switching between lenses or carrying around multiple focal lengths in your camera bag. While kit lenses often have a relatively narrow aperture, and therefore a longer depth of field, you can also find wide aperture 28-70mm AF and AT-X lenses for capturing super-sharp images in low-light conditions.

What Are the Advantages of a 28-70mm Camera Lens?

A 28-70mm camera lens covers a focal range closely associated with what the human eye sees, which makes it an easy lens for photographers to work with when they are just starting. It's a practical option when you want a lens that you can just leave on your camera body, and perhaps string around your neck when on vacation, ready to capture candid moments at a second's notice.

• A zoom lens with a 28-70mm focal range eliminates the need to carry multiple lenses, such as a wide angle, 50mm portrait lens and a short zoom, as it can cover all ends of the spectrum. It is also much lighter than a telephoto zoom, so a good addition when you are trying to keep your travel photography kit lightweight and compact.
• In addition to capturing wide angle landscape shots and beautiful portraits, you can also use an AF 28-70mm to get up-close to subjects in their natural world. Most have a relatively short minimum focusing distance, although not as close as a dedicated macro lens.

What Should You Look for When Buying a 28-70mm Camera Lens?

The zoom lens that's right for you depends on the depth of field and image sharpness you want to be able to achieve. Lenses with wider maximum apertures enable you to photograph images with beautifully blurred backgrounds and bokeh effects while still being able to use fast shutter speeds to capture sharp images in low-light conditions.

• In addition to big-name camera brands and their lenses, you can also find third-party lens manufacturers, such as Tokina, which produces the AT-X 28-70mm with many optical technology features.
• Look for Tokina AT-X lenses that are the company's top-of-the-range models, using the most advanced design and fabrication technologies available. You can find AT-X lenses with autofocus (AF) capabilities, as well as those with wide maximum apertures for image sharpness.
