Having a 10x zoom on a camera phone is no mean feat: it means the device will offer a zoom ranging from
15.9mm to 159mm
(the equivalent of). So, how does this zoom work – given there’s such a small area on a phone to cram the necessary lenses in?
What does 2x optical zoom mean?
Taking the focal length of the telephoto lens and dividing it by the focal length of the
wide-angle lens
will give you the zoom range of the camera. For example, if a phone has a telephoto lens with a 52mm focal length and a 26mm wide-angle lens, this gives you the zoom range of 2x optical zoom.
What is 10x optical zoom equivalent to?

What is a good optical zoom?
It’s common to see compact cameras with
20x or 25x optical zoom
. … High zoom capabilities don’t always translate into the best image quality. You need the perfect combination of a powerful zoom lens and an equally powerful sensor to capture razor-sharp images every time.
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.
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.
What is 50x optical zoom?
The 50x optical zoom lens is
a 35mm equivalent of 24-1200mm
, which can be extended to 100x using Zoom Plus. Thanks to its Ultra Sonic Motor the lens has near-silent zooming. To help take the sharpest shots possible there is 4.5 stop optical image stabilisation.
How does optical zoom on phones work?
Zoomed images are made using
a composite of multiple images shot
, as the optical image stabilization motor moves the camera slightly during capture. It’s used to emulate the data that would be captured by a higher-resolution sensor, as that movement is so slight it captures detail between the ‘real’ pixels.
What is 2x optical zoom on iPhone?
The iPhone XS
has a 2x shortcut on the camera interface that allows you to switch to the closer telephoto lens with the press of a button (basically, toggling between the two lenses). The button also turns into a slider tool to zoom in up to 10x one-handed, which is especially helpful for when you’re shooting video.
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.
Is it better to have more megapixels or optical zoom?
Optical zoom is ultimately better
, as it magnifies an image to fill the entire image sensor — say, 10 megapixels worth. Digital zoom takes just the center portion of what the lens threw on the sensor, capturing fewer pixels, say 6MP. … Made-up pixels won’t show the same, accurate detail as the real thing.
How much zoom is enough?
A zoom of
25x or more
should be all you need for your average high-school auditorium. Try out your zoom before the show, and if you’re far away, ask someone if you can record from up from on either side of the stage (so you’re not in anyone’s way). Your video will look much better.
Which camera has the highest zoom?
Japan-based optics and imaging products pioneer Nikon has launched a camera with the world’s highest optical zoom. Called the
Coolpix P1000
, the camera comes equipped with a 125x optical zoom lens that covers the wide-angle 24mm to super-telephoto 3000mm focal lengths.
What is 20x optical zoom equivalent to?
Its “focal length equivalent” is from
28-560mm
(which is where the 20x number comes from, and also approximates what the focal length of lenses would have to be on a 35mm film camera or full-frame dSLR.)
What is 25x zoom?
A 25x zoom simply means
the longest focal length is 25 times the shortest focal length
. So a 24-600 means that 600/24=25 times. The 18-400 is a 22x focal length, but the effective focal length is 27-600mm on the Nikon camera.
How far can you see with 100x zoom?
At 100x magnification you will be able to see
2mm
. At 400x magnification you will be able to see 0.45mm, or 450 microns. At 1000x magnification you will be able to see 0.180mm, or 180 microns.
