Optical Zoom vs. Digital Zoom: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Optical Zoom uses camera lens mechanics to bring subjects closer, maintaining image quality. Digital Zoom enlarges the image digitally, often reducing quality.
Key Differences
Optical Zoom involves physically moving the camera's lens to magnify the subject, preserving image resolution and clarity. In contrast, Digital Zoom works by cropping and enlarging the image digitally, which can lead to a loss of image quality as it relies on software rather than lens optics.

Optical Zoom is achieved through the camera's hardware, allowing for close-up shots without compromising on image detail. On the other hand, Digital Zoom simply enlarges the pixels in the image, often resulting in pixelation and a decrease in image sharpness.
