Getting it sharp from a telephoto

Telephoto prime and zoom lenses are among the most useful lenses for a wide variety of genres. They are used for sports, wildlife, travel, and street photography. Many photographers use them for portraits and close-up shots as well.

Technically, telephoto lenses have a focal length or 60mm or more for a standard 35mm or full sensor size camera, though most people think of telephoto lenses having a focal length of 85mm or more. Lenses with a focal length greater than 300mm are considered to be super-telephoto lenses.

Telephoto lenses help us bring distant subjects closer, fill our frame with the subject, show detail difficult to see, capture action, and produce a shallow depth of field.

Lenses for Travel Photography - Part III (Choosing between zoom and prime lenses)

This week in Part III of my seven part series about lenses for travel photography, I’ll discuss ideas you can use to help you choose between zoom and prime lenses. The series is primarily meant for SLR and DSLR camera users, who can attach a variety of lenses to their cameras to support their creativity, and suit the needs of their photographic opportunities.

Before you can choose between these two types of lenses, you have to understand the difference.

Simply put, prime lenses are lenses with a single focal length. Prime lenses come in a large number focal lengths ranging from wide angle through super telephoto.

Zoom lenses are lenses which have a variety of focal lengths within just one lens. Zoom lenses can have focal lengths which are all within one class of lens, such as the Sigma 10-20mm f/4-5.6 EX DC HSM Lens, which stays solely within the wide angle range of focal lengths. Zoom lenses can also have focal lengths which span lens classes such as the Nikon 18-200mm f/3.5-5.6 G ED-IF AF-S VR DX Lens which runs the gamut from wide angle, through normal, to telephoto focal lengths.
