WHAT is zoom lens in camera?

How do you zoom in on a video camera?

Why do most DSLR cameras come with zoom lenses instead of prime lenses?
The reason why prime lenses are the more popular choice when it comes to capturing accurate and tack sharp images is because zoom lenses will always tend to be more prone to distortion and chromatic aberration, especially towards the wider and tighter ends of the lens.
What optical zoom is best?

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).
What is 12x zoom?
The “12×” is a ratio – all it says is that the longest focal length is 12 times longer than the shortest one. A 10–120mm lens is a 12× zoom, but so is a 100–1200mm lens.
What does 35x optical zoom mean?
Say you buy a compact camera with a whopping 35x zoom. That sounds better than your DSLR lens with an 8x zoom, but this doesn’t mean that things look 35 times bigger than they do with your eyes. Instead, it means the ratio between the shortest and the longest focal length of that lens is 1:35.

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 the disadvantage of zoom lens?
Zoom lenses do have some disadvantages compared to prime lenses that you should take into consideration. A zoom lens is usually not as sharp as prime lenses. Another is that a zoom lens is slower. Because the maximum aperture of a zoom lens is narrower, it lets less light pass into the camera.
