Glossary Of Photography Terms [1]

Optical Viewfinder An optical viewfinder is a viewing system built into cameras that allows photographers to compose and frame their shots by looking through an optical window or eyepiece. Optical viewfinders utilize a series of mirrors and prisms to reflect the scene directly from the camera's lens to the viewer's eye, providing a real-time, optical representation of the subject without any electronic processing.
Optical viewfinders offer several advantages, including a clear and bright view of the scene, minimal lag or delay in image preview, and reduced power consumption compared to electronic viewfinders (EVFs). They are commonly found in DSLR (Digital Single Lens Reflex) cameras and some rangefinder-style cameras. While optical viewfinders provide a direct and natural viewing experience, they may have limitations in displaying exposure settings, focusing aids, and other digital overlays compared to electronic viewfinders. However, many photographers prefer optical viewfinders for their immediacy, clarity, and familiarity in composing and capturing images.
