What is the Difference between Optical Zoom and Digital Zoom
Digital cameras have made it very easy and affordable for people to take pictures of the memorable days and keep them forever. The onetime cost of buying digital cameras have saved the life time cost of getting prints from film that adds extra cost. Even photography has become easy for many those people, who could not buy a photographic camera with great zoom ability. But many times cameras are sold on the quality of having digital or optical zoom. Both sound amazing but what do they mean! This is what interested people can find in the upcoming lines.
Optical Zoom
Optical zoom means the clones of the object achieved through the lens of the camera. The closer the object is the better than its details. Optical zoom does not decrease the image quality as it actually works like binocular, which can take the object closer without losing its clarity. The outer lens of the camera moves at the distance required like 2x, 4x or 8x to get the image doubles, or 8 times bigger. The more optical zoom a camera offers, the better is to buy it.
Digital Zoom
Digital zoom is not about drawing the picture closer but it is expanding the picture. It works exactly like zooming the image on PC. The image looks bigger but not zoomed. This decreases the image quality as during expanding the square blocks on the image and hence the image loses its quality.
Optical Zoom vs Digital Zoom
Optical zoom means to draw the object closer to the lens by moving the lens closer to the object while digital zoom means to expand the image by not moving the lens. Optical zoom remains as clear as un-zoomed while digital zoom becomes somewhat blur. Optical zoom can achieve greater closeness with the same quality of the image while in digital zoom the more you expand the picture, the more it loses its image quality.
