Camera lenses fall into one of two categories. Prime lenses are set to one specific focal length, and they are normally faster than zoom lenses along with having faster maximum apertures. They also tend to weigh less. Many photographers choose to upgrade to fast prime lenses because of their ability to let a lot of light in. There are many different types of zoom lenses including:
- Standard: These general-purpose full frame lenses usually offer wide-angle possibilities along with moderate telephoto options. A typical standard offers a range from 16 to 85 millimeters with an F-stop range from 3.5 to 5.6 or a range from 17 to 55 millimeters with an F-stop of 2.8.
- Telephoto: These lenses allow you to get closer to your subject. A typical one offers a range from 55 to 200 millimeters with an F-stop range from 4.5 to 5.6 or a range from 75 to 300 millimeters with an F-stop range from 4 to 56.
- Superzoom: These lenses combine the benefits of a telephoto lens and a standard lens. A typical superzoom lens offers a range from 55 to 200 millimeters with an F-stop range from 4.5 to 5.6 or a range from 75 to 300 millimeters with an F-stop range from 4.5 to 6.
- Macro: These fixed-focal-length lenses are designed to let you get close to small objects. A typical macro lens is 60 millimeters with an F-stop of 2.8.
Many lenses offer auto-focus with different manufacturers using unique systems. It is essential to choose the one that is right for your camera body. Choices include:
- Screwdrive: These lenses rely on the camera's body to do the focusing.
- Micromotor: These lenses use a DC motor and a gear train to focus the image.
- Linear Stepper: These lenses have a brushless motor, making them a quiet option.
- Ultrasonic-type: These silent lenses can be overridden with full-time manual focus. Some companies refer to these lenses as hypersonic, silent wave, or silent drive.
The process of choosing a new lens is quite simple:
- Select lens mounting system: Look in the manual to find the lens mounting system as different systems use various methods to mount lenses. The age of your camera also makes a difference.
- Select focal length: Consider what you plan to photograph so that you can choose the correct focal length.
