How does zoom work?
On an ordinary camera with a zoom lens, optical zoom works by mechanically moving the glass elements within the lens to magnify the image. Digital zoom, on the other hand, is completely software reliant.
What is a zoom lens?
A zoom lens, on the other hand, is made up of several glass elements inside that move back and forth in relation with each other in order to magnify the image (zoom in) or make it smaller (zoom out). As these glass elements move, the focal length changes. For example, a lens that is said to 18-55mm means that it can change its focal length ...
What is optical zoom?
Optical Zoom On Smartphones: What Is It Really? These days, when looking at smartphone camera specs, optical zoom has increasingly become a major talking point by phone manufacturers. That's because in the past, phone cameras have only been able to use digital zoom, but now technology has made optical zoom a reality.
Why do some smartphones have zoom?
Digital zoom is actually one of the reasons why some smartphone manufacturers pack their cameras with a lot of megapixels. The more megapixels a camera has, the more the picture can be blown out without an overly noticeable reduction in picture quality.
Why is hybrid zoom used?
To get the best results, smart algorithms are employed to grab the data from all the cameras and use it to put together an image with as little apparent picture degradation as possible while zooming in.
What is Digital Zoom?
Digital zoom expands the size of pixels in a digital image, making it appear bigger. At some point, you’ll actually be able to see the pixelation, making the image look “blocky”. It’s far better to optically zoom into an area of observation first for the highest quality footage. You can always apply a digital zoom at a later point if you’d like.

What is optical zoom?
Optical zoom measures the actual increase in the focal length of the lens. Focal length is the distance between the center of the lens and the image sensor. By moving the lens farther from the image sensor inside the camera body, the zoom increases because a smaller portion of the scene strikes the image sensor, resulting in magnification.
What is a multiplier lens?
In other words, the "multiplier" is the difference between the smallest and largest focal length measurements of the lens. 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. However, if the digital camera offers some additional wide-angle capabilities ...
How to measure optical zoom?
With an interchangeable lens camera, you can calculate the optical zoom measurement yourself by using a simple mathematical formula. Take the maximum focal length that the interchangeable zoom lens can achieve, say 300mm, and divide it by the minimum focal length, say 50mm. In this example, the equivalent optical zoom measurement would be 6X.
Why is it important to understand the zoom lens?
It's important to understand the zoom lens because the two types of zooms are vastly different from each other. In the battle of optical zoom vs. digital zoom, only one — optical zoom — is consistently useful for photographers. With most digital cameras, the zoom lens moves outward when in use, extending from the camera body.
Why is my camera blurry?
Slower shutter response time: When using the maximum zoom magnification, the shutter response time sometimes slows, which may cause blurry photos. You also could miss a spontaneous photo because of the slower shutter response. It simply takes the digital camera longer to focus on the image at the maximum zoom setting, which explains the slower shutter response time. Such problems are magnified when shooting at maximum zoom in low light.
What does a larger number mean on a camera?
A larger number signifies a stronger magnification capability. Keep in mind that not every camera's "10X" optical zoom measurement is the same. Manufacturers measure the optical zoom from one extreme of the lens' capabilities to the other.

RAW files are much larger because they capture all of the data your camera sees. In comparison, JPEG files compress the image for you automatically, so these files are much smaller. Professionals will generally shoot in RAW, as the format gives them more control in the editing process.
Which is better, a 20 megapixel or a 16 megapixel camera?
Most people spring for the camera with the highest resolution, measured in megapixels. A 20-megapixel camera theoretically takes better pictures than a 16-megapixel one, but this isn’t always the most telling spec when it comes to performance. Instead, look at the sensor size. A larger sensor will capture more light and produce images with less noise.
Can you adjust the focus on a P1000?

What is the best zoom for indoor photography?
Again, a low zoom (2x to 5x), wide perspective camera would be excellent. If you’re taking an outdoor shot, space won’t be much of a bother and you’ll also want to take pictures of things far away. This calls for a larger optical zoom (5x or more) and a decent perspective.
What is the difference between focal length and optical zoom?
The focal length (read as ‘XX’mm) is the strength with which the lens can focus on an object, while the optical zoom (the number ‘X’x zoom) is the strength of the total zoom you can achieve. This means that if a lens has a larger focal length, it has a narrow angle of view and a smaller focal length implies a wider angle of view.
