What does 30x optical zoom mean?

30x optical zoom. Extend your reach to the max with this fast 27 mm – 810 mm f/2.8-5.6 Carl Zeiss Vario Sonnar T* lens. 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.

How far can 20x optical zoom See?

The 20x refers to the amount of magnification. This zoom magnifies 20 times so if you were taking a picture of something 20 feet away it would appear to be 1 foot away. 100 feet away would appear to be 5 feet away. Optical zoom is the best versus digital zoom.

What does 40x optical zoom mean?

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).

What does 50x optical zoom mean?

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.

Which is better optical or digital 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.

How much optical zoom is good for a digital camera?

You will need a great deal of optical zoom, at least 10x. If you're taking single subject pictures without much interest in the surroundings, then a narrow perspective camera with 10x or 15x optical zoom is excellent in getting the right kind of detail, like the lion's eyes or the eagle's beak.

What is 10x optical zoom?

The Higher the Optical, the Better

In a still camera, an optical zoom of 10x or more is called a "superzoom" lens. Note that if a still camera is advertised with "10x zoom," that does not necessarily mean optical zoom only. In many cases, the optical is 3x with the additional 7x being digital.

How far does 10x zoom go?

Zooms on digital camcorders are defined by how many times closer to an object your video will look as compared to using no zoom at all. For instance, a 10x zoom will bring you 10 times closer to an object, whereas a 100x zoom will bring you 100 times closer.

How do you calculate optical zoom?

To determine the overall zoom ratio of the lens, simply divide the longest focal length by the shortest. So, for example, the Sigma 18-35mm F1. 8 DC HSM and the 8-16mm F3. 5-4.5 are both examples of 2x zoom lenses: 35 divided by 16 equals 1.95, and 16 divided by 8 equals 2.

What is a good optical zoom for a camera?

Superzoom explained

The whole point of a compact camera is to provide a great quality image within the constraints of the compact body and its fixed lens. Luckily, fixed camera lenses can now produce amazing zoom ranges. It's common to see compact cameras with 20x or 25x optical zoom.

How many times zoom is 300mm?

When they say "X amount of zoom"...they are just comparing the minimum focal length to the maximum focal length. The 75-300mm lens for example. 300mm is about 4 times as long as 70mm...so it's a 4X lens.

Does optical zoom reduce 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.
