Lenses

Prime Lens (Fixed Focal Length Lens): Prime Lenses have a set focal length and therefore can not vary their angle of view.

Zoom Lens: Zoom Lenses have the ability to vary their focal length (and thus angle of view).

Fish-eye Lenses
In 35mm: 8mm - 15mm

A fisheye lens is a wide-angle lens that takes in an extremely wide, hemispherical image.

Wide-Angle Lenses
In 35mm: 20mm - 40mm

These lenses let you capture more by broadening the angle of view and increasing the depth of field bringing more area into focus. By expanding the apparent distance between the foreground and background, they provide a unique perspective.

Standard Lenses
In 35mm: 50mm

For a more natural angle of view and perspective choose a standard lens. These lenses will provide you with the image closest to how your eye perceives the subject and for giving images natural depth of field.

Telephoto Lenses
In 35mm: 100mm - 300mm

Telephoto lenses not only let you close-in on a subject, but also allow you to zoom in on a subject that you cannot get close to. The longer focal lengths effectively compress the distance between the subject and camera to capture the details and the feeling of a far-off scene.

Super Telephoto
In 35mm: 400mm - 800mm

Nothing quite compares to the amount of dimension a super telephoto lens can bring to a photograph.

Field of View Crop Factor

With the advent of digital camera bodies, the term Field of View Crop Factor has come into our world. The source of this term is the smaller-than-35mm sensor present in many digital camera sensors. DSLR lenses still focus the image on the same plane as before, but sensors smaller than 35mm sensors do not capture the entire image. Thus, the image is "cropped". The Field of View Crop Factor refers to the amount of the image that is cropped.

Field of View Crop Factor

When buying a camera or looking at your camera's technical data you may come across "35mm equivalent". This is a way of communicating the relative angle of view the lens achieves.
