Some cameras use that to have artificially high megapixel values. But half of those pixels come out of its @$$. yea, digital zoom is bad, its basically cropping the picture and decreasing detail… you can get the same effect as digital zoom by using the crop tool in photoshop, for example.
In the same way What is one disadvantage of using digital zoom?
One disadvantage of using digital zoom is that as you keep zooming in the picture will get blurry or grainy. Changing the file size in the camera accomplishes many things.
Subsequently, Which is better digital zoom or optical zoom? Despite all the advancements in cameras and digital magnification, optical zoom is better. … If you then zoom in to 100mm your image will still be 10MP. But with digital zoom cameras, the megapixel resolution decreases as you zoom into the image. This is because your digital camera is cropping your images.
Is digital zoom just cropping?
Digital zoom is a restricted form of cropping: It is always done around the center. It is constrained to certain fixed increments. It is limited in quality by the firmware of the camera.
Do DSLR cameras have digital zoom?
Which Camera Lenses Can Zoom? While only film cameras allow for optical zoom, both film cameras and digital cameras (including point-and-shoot cameras, DSLRs, mirrorless cameras, and video cameras such as camcorders) have the possibility of using digital zoom, depending on the lens you’re using.
Does zoom affect picture quality?
Optical zoom does not affect the pixels of the captured image, and therefore maintains the same image quality at all focal lengths. Digital zoom does not depend upon how the lens itself is built, and instead is achieved by digitally magnifying the image captured.
What does 30x optical zoom mean?
The 30x magnification range is nothing short of incredible, allowing you to zoom up to distant subjects while still maintaining the clarity that only optical zoom can provide. … And by combining this function with Digital Zoom, up to 120x zoom* can be achieved without sacrificing image quality!
What is difference between zoom and optical zoom?
Optical zoom leverages the physical change in a lens to adjust the distance between camera sensor and subject, whereas digital zoom uses magnification technology to enlarge an area of an image (thereby compromising the integrity of the picture by cutting down on the megapixels).
What does 60x zoom mean?
Pushing the zoom limit to 60x optical means that birdwatchers and some long-distance sports photographers will be happy. The lens itself is reasonably wide at 24mm and extends to 1440mm (35mm equivalent). … Also in the lineup is the S9700 which comes with a 30x optical zoom lens, but in a much smaller overall package.
What does 10X zoom mean?
Understanding Zoom Measurement
A larger number signifies a stronger magnification capability. … For example, if a 10X optical zoom lens on a digital camera has a minimum focal length of 35mm, the camera would have a 350mm maximum focal length.
What do you mean by megapixel?
One megapixel refers to one million pixels, which are small squares of information that combine to make up an image. So, if a camera has a resolution of eight megapixels, it would be able to capture images with about eight million tiny squares of information per inch, as About.com’s photo expert explains.
What does 4x zoom mean?
The 4x Zoom means that beyond the 10x optical zoom, the camera will electronically jack it up another 4 times. However, it does so by blowing up the pixels and it can make the photos grainy.
Is it better to zoom or crop?
Cropping is the better option than zooming in. Cropping a photo on your iPhone is better than zooming in before capturing it. … Although, take note that both zooming in and cropping reduce the quality of a photo. So, if you’re choosing to walk the less evil path of cropping a photo, don’t overdo it!
Is 40x optical zoom good?
Its 40x optical lens means it can capture from an equivalent 24mm wide-angle (wide enough for shots of groups, say, or landscapes), through to a massive 960mm equivalent (long enough to pick out far-away subjects and make them appear close-up within the frame).
Is 50x optical zoom good?
The 50x optical zoom alone is the focal length equivalent of 24-1,200mm on a full frame body. The 4x digital zoom brings that up to 4,800mm equivalent, but you’re still probably better off sticking with the optical and scaling in post if you need to. That being said, it’s still pretty impressive.

But with digital zoom cameras, the megapixel resolution decreases as you zoom into the image. This is because your digital camera is cropping your images.
What is 12X optical zoom?
Ideal for high magnification applications requiring the optimal balance between optical performance, large zoom range and price, the 12X offers incredible 12X (0.58-7X) magnification, increased resolution with 0.004-0.550 N.A., and unmatched edge flatness and clarity.
How far can 50x zoom See?
The 50x optical zoom alone is the focal length equivalent of 24-1,200mm on a full frame body. The 4x digital zoom brings that up to 4,800mm equivalent, but you’re still probably better off sticking with the optical and scaling in post if you need to.
What is 42x zoom?
An optical zoom lens can use almost any wide-angle or telephoto focal length setting. … If a 42x optical zoom lens has a wide-angle setting of 25mm, then its maximum telephoto setting would be 1050mm (25 multiplied by 42).
What does 60x zoom mean?
Let’s look at the most interesting camera first, which is the P600 superzoom. Pushing the zoom limit to 60x optical means that birdwatchers and some long-distance sports photographers will be happy. The lens itself is reasonably wide at 24mm and extends to 1440mm (35mm equivalent).
Is 10x optical zoom enough?
At least 10x zoom is needed, but 50x optical zoom or even more is better. Many professional wildlife photographers go for very long lenses that enable them to photograph wildlife from a significant distance. If you can’t afford a lens with a long focal length, then a high zoom range is what you should go for.
