There are many different parts that camera lenses often share in common, including:
- Optical lens: This glass on the front of the lens focuses light into the cameras body.
- Filter threads: These threads allow the photographer to attach different filters to the camera.
- Focusing ring: Turning this ring focuses the image.
- Focal length ring: When present, turning this ring adjust the focal length.
- Aperture ring: This ring controls how much light gets into the camera.
- Aperture: This small opening adjusts how much light gets to the film or image sensor.
- Lens mount: This part is used to attach the lens to the cameras body.
A prime lens has a fixed focal length. Therefore, you have to change your position if you want to add or subtract elements from a photo. Prime lenses have fewer moving parts. They may have larger apertures, allowing photographers to take pictures in low-light conditions. Prime lenses come in a variety of focal lengths.What are some variable types of camera lenses?
There are many different types of variable camera lenses, including:
- Wide-angle: These options usually have focal lengths between 17 millimeters and 40 millimeters. They often allow photographers to capture wide-angle views of a scene.
- Standard: These options usually have focal lengths between 40 millimeters and 60 millimeters. Most are designed to capture images like the naked eye sees them.
- Telephoto: These options usually have focal lengths above 70 millimeters, and they may be used when capturing images where the photographer cannot get close to the scene.
- Fish-eye: These options usually have a focal length of fewer than 15 millimeters. They are designed to provide a 180-degree view.
- Micro: These options allow the camera to capture images of extremely small objects. They come in a variety of focal lengths.
The f-stop is how much light is allowed to enter the camera as it controls the aperture. In turn, it also controls your depth of field. As a general rule:
- F1.4 lets in a huge amount of light while creating a thin depth of focus.
- F2.0 to F2.8 let in less light, creating a thin depth of focus.
- F4.0 to F5.6 are considered the middle of the f-stop scale; these settings create a moderate depth of field.
- F8.0 to F 11.0 let in little light while creating a large depth of field.
- F16.0 and above let in little light while creating a huge depth of field.
