A camera lens and sensor are two different components of a camera that work together to capture images.
- Camera Lens: The camera lens is the part of the camera that focuses light onto the camera sensor. It is responsible for controlling the amount of light that enters the camera and for focusing the image onto the sensor. Camera lenses come in different focal lengths and apertures, which affect the field of view and depth of field of the image.
- Camera Sensor: The camera sensor is the electronic component in a digital camera that captures the image. It is made up of millions of light-sensitive pixels that convert light into electrical signals, which are then processed by the camera's image processor to create a digital image. The size and quality of the camera sensor can affect the resolution, dynamic range, and low-light performance of the camera.
In summary, the camera lens controls the light entering the camera and focuses the image onto the sensor, while the camera sensor captures the image and converts it into a digital format. Both components are essential for capturing high-quality images.

Lens
- Function: Collects and focuses light onto the image sensor.
- Characteristics:
- Focal length: Determines the field of view and magnification.
- Aperture: Controls the amount of light entering the lens.
- Optical quality: Affects image sharpness, color accuracy, and distortion.
- Lens type: Includes prime (fixed focal length) and zoom lenses (variable focal length).
- Mount: Connects the lens to the camera body.
Image Sensor
- Function: Converts light into electrical signals that create the image.
- Characteristics:
- Size: Larger sensors capture more light and produce better image quality.
- Resolution: Determined by the number of megapixels. Higher resolution means more detail.
- Type: Includes CMOS (most common) and CCD (older technology).
- Sensitivity (ISO): Measures the sensor's ability to capture light in low-light conditions.
- Dynamic range: The difference between the lightest and darkest areas that the sensor can capture without losing detail.
Key Differences
- Function: Lens collects light, while the sensor converts light into an image.
- Location: Lens is attached in front of the camera body, while the sensor is located inside.
- Physical Characteristics: Lenses vary in focal length, aperture, and mount type; sensors vary in size, resolution, and sensitivity.
- Impact on Image Quality: Both lenses and sensors play a crucial role in determining image sharpness, colors, and overall quality.
- Interchangeability: Lenses can be swapped to achieve different effects, while sensors are typically fixed within the camera body.
- Function: Collects and focuses light onto the image sensor.
