FAQ

What does auto focus lens mean?

Autofocus (AF) refers to the ability of a camera to automatically focus on a subject; there are multiple methods of AF, and the range of focus (distance measurement point) can be set by the focus area. The latest AF systems not only focus accurately, but also track moving subjects.

Manual Vs Autofocus

The difference between manual vs. autofocus lenses is that AF lenses do most of the focus work for you, while with manual lenses, you must adjust the focus by hand. With a manual lens, you control what your camera focuses on rather than letting the lens technology decide. Manual lenses are commonly the ideal choice for:
• macro photography
• deep landscape photography
• night sky photography

Autofocus lenses come with many advancements and additional technologies, such as facial recognition and tracking, which allow the lens to pinpoint its subject. Autofocus lenses are commonly the ideal choice for
• kids playing
• birds in flight
• people walking down the street
• sporting events
• pets
