Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
The camera under test senses a real image of the virtual image of the target, and the sensed image is displayed on a monitor. [9] Monitor display of sensed image from the camera under test. The sensed image, which includes the target, is displayed on a monitor, where it can be measured.

View camera lenses are designed with both focal length and coverage in mind. A 300 mm lens may give a different angle of view (either over 31° or over 57°), depending on whether it was designed to cover a 4×5 or 8×10 image area. Most lenses are designed to cover more than just the image area to accommodate camera movements.
The lens is focused automatically by means of the camera's hardware and firmware, to obtain optimum sharpness of an image. [4] AF-L or AFL: Autofocus lock. Locks a particular focus setting, preventing refocusing if the scene changes. [4] AoV: Angle of view. Describes the angular extent of a given scene that is imaged by a camera. APEX
The image has been deliberately overexposed by +1 EV to compensate for the bright sunlight and the exposure time calculated by the camera's program automatic metering is still 1/320 s. The purpose of an exposure meter is to estimate the subject's mid-tone luminance and indicate the camera exposure settings required to record this as a mid-tone.
