Choosing the right camera was a dilemmatic process. Hours of research and recommendations from colleagues and friends finally led me to the camera I am using now. That was the time when I came across a very significant choice to make: optical vs. digital zoom. It's indispensable that you know the difference between optical and digital zoom and how zoom can affect your image quality.
Maybe I should go for Optical Zoom. Wait! What is that?!
A great many people, eventually in their life, have utilized optical zoom. Optical zoom is the conventional strategy for zoom, whereby, you utilize the optics of the long-range focal points to carry the subject nearer to your picture sensor. We have presumably observed a zoom definition showed as a number, for example, 2x, 4x, etc. These mean the amount we can amplify a picture and different lenses can accomplish distinctive optical zoom ranges. For instance, with 8x optical zoom, it would mean that we can amplify the picture up to 4x bigger.
Okay great. But what about Digital Zoom?
Despite the name, the digital zoom does not mean to zoom into a scene. The term is originated from digital camcorders and works by trimming into the center segment of the picture and enlarging it. Digital zoom works similarly to software such as Adobe Photoshop where we can also crop the image and enlarge it. However, utilizing a digital zoom will compromise the quality of the image.
I’m still confused, just help me decide. Which one is better?
Camera with digital zoom compromises on the megapixel resolution as we zoom into the image. The reason for this is that the digital camera initially crops the image and then enlarges it to fit the original size. This would mean that there are fewer pixels in a similar size zone of the image and to solve this matter digital cameras at that point include some "made-up pixels" to bridge the gap. However, these additional made-up pixels lack the degree of detail as optical zoom and therefore affect the quality of the image.
Hencem I feel that optical zoom is better and can illustrate it with the following example. Let us say that I am using a 10 MP camera with an optical zoom lens of 12x. Whether at a focal length of 40mm, 50mm, or even 100mm, the quality of the image will be at an uncompromised 10 MP.
So that means that I should steer clear of cameras with Digital Zoom?
The answer is well, not necessarily. The main thing we should be aware of is that digital zoom on cameras has improved significantly throughout the years. Truth be told, even my cell phone uses digital zoom! It is not a yes or no answer but instead figuring out how to utilize digital zoom in the most ideal manner.
The most effective and appropriate manner to utilize “digital zoom” is through means of post-processing software, such as Adobe Photoshop. Rather than focusing in on the camera, snap the picture and afterward crop utilizing the editing software. The advantages of this technique are that we will have more command over the editing of the image. Additionally, the image won't be compromised by the camera including made-up pixels into it, which deteriorates its quality. Inclusive is the choice of returning to the primary crop of the picture, an option that is not present in the event of utilizing a digital zoom.
If the objective is utilizing your picture at bigger sizes, at that point digital zoom may not deliver the best outcomes. However, in the event you are printing smaller photographs, such as 6x4s, then even a digital zoom ought to do the trick!
What would be the Ideal Optical Zoom?
That is dependent on what you would like to photograph. Let’s say I am interested in wildlife photography that would require me to have an optical zoom of 20x or even 40x as opposed to a 2x, which won't help get sufficiently close to the creature. However, if landscape photography piques my interest, I would not be required to zoom in way too much. In that case, 2x optical zoom may get the job done. In conclusion, we should consider what kind of photography we’re interested in and purchase the optical zoom accordingly.
Optical zoom vs digital zoom? Which one? When in doubt, I would consistently suggest that you pick optical zoom hands down over digital zoom. On the off chance that you are hoping to purchase a digital zoom camera, consider one that permits you to halt digital zoom, or on the other hand, one that cautions you that you are going to utilize the digital zoom.
Regardless of whether you choose to purchase another cell phone or a mirrorless camera, the choice of optical zoom vs digital zoom is one that you ought to consider cautiously. The distinctions referenced in this article among optical and digital zoom can assist you with choosing which zoom is best for you.
