Latest company news about Unveiling the Difference: Optical Zoom vs. Digital Zoom

It is considered that the ability to zoom in is one of the most important aspects when capturing outstanding images. Nevertheless, the type of zoom can have a big effect on the final quality of the picture. in this post, we shall discover more about the optical and the digital zoom and be in a position to make a better decisions for our need for the kind of photography that we want.

Optical Zoom
Optical zoom or referred to as true zoom is the ability to bring the subject closer by altering the actual lens without losing the quality of the image. This kind of zooming system involves a mechanical system of lenses that shifts to make the subject larger, this delivers a real enlargement of the image at the same time giving a crisp image.


Optical zoom Camera

The major positive effect of optical zoom is the preservation of the image resolution as well as the reality. At the larger settings, you can get a large field of view and the picture tightens up because the lens is physically moving to take a closer look at the subject. This means that optical zoom is the most cherished by the specialists and those ones who value picture quality.

Digital Zoom
Digital zoom, in contrast, is the kind that enlarges the image through software after the picture has been captured by the sensor of the camera. Unlike optical zoom, the digital zoom just enlarges a certain part of the picture by cutting and reducing it and it is, therefore, not as sharp or clear.

The major downside of using digital zoom is that despite making the subject appear larger it actually crops the image and enlarges it, which more often than not results in a grainy, pixelated low-quality picture. This is mainly the case with digital zoom, which, in fact, is nothing more than an enlargement of the captured image using a restricted area of the sensor.


Which One is Better?
When it comes to choosing between optical and digital zoom, the answer is clear: The optical zoom will always be the preferred over the digital so that good pictures can be taken.


Digital zoom usually creates a lower-resolution and enlarged image that loses quality when zoom is at its maximum point. This makes it the favorite for activities like wildlife, sports, or shooting distant objects such as scenes view or large landscapes where a close shot to the subject is important but not at the cost of quality.


Digital zoom, on the other hand, should be used when it is needed to just crop the photo or when taking snapshots. If you need to do a fast and spontaneous photo, or adjust the image maybe two or three points around the shooting area after the picture is taken, then handy, however, it is not suitable for systematic photography or print-outs.



Q: As for zoom for video, which is better?
A: For using lenses, optical zoom should be opted in case of videos as it does not lose the video quality and sharpness even on full zoom. Digital zoom is advisable to be shunned when it comes to video, as this will lead to pixelation and hence low quality.


Q: Does the number of megapixels impact the qualities of an Optical & Digital zoom in a camera?
A: The megapixels of a specific digital camera affects the number of the total pixels that are present on the camera sensor; it does not determine the disparity between the optical zoom and the digital zoom. Higher end sensors will benefit both kinds of zoom, as before, though optical will retain its edge in that respect.


In photography, it is very important to differentiate between the optical and the use of digital zoom in order to get better pictures. Digital zoom is better for amateurs and simple picture taking Occasionally though, some devices use digital zoom and add a message that optical zoom is far better for serious photographers because at the maximum zoom level, it doesn’t reduce the quality of the picture taken. Conversely, digital zooming is more capable of delivering acceptable results for most simple photo captures or scenarios where image quality is secondary.


There is ample choice in zoom lenses starting form compactpoint-and-shoot camers up to professional DSLRs, thus it will be easy for anyphotographer to select the type of zoom that will suit his photography projectbest. Therefore, when out capturing memories, should remember the difference between an optical and a digital zoom and what each can do for and to you.
