FOCOMETER Meaning and
Definition
-
A focometer is an optical device used in the field of photography and cinematography for measuring and adjusting the focus of a camera lens. It is specifically designed to accurately determine the distance between the camera and the subject or the distance between two objects within the frame.
The primary purpose of a focometer is to ensure that the subjects being photographed or filmed are in sharp focus. By measuring the distance between the camera and the subject, this device aids in achieving optimal clarity and sharpness in the captured image. It is especially useful in situations where automatic focusing systems may not be reliable or available.
Focometers generally consist of an eyepiece, a viewing window or scale, and a movable cursor or marker. The user aligns the cursor with the subject they want to focus on and reads the distance value indicated by the scale or window. Some focometers may also feature additional scales or indicators to assist in achieving precise focus.
This device is commonly used by professional photographers, cinematographers, and filmmakers to ensure high-quality visuals and maintain creative control over the focus of their shots. With the advancement of autofocus technologies, the use of focometers has become less common in recent years. However, they still serve as a handy tool for photographers working with manual focus cameras or lenses, or when optimal accuracy and control are required.
