What are the main differences? In short, with optical zoom you first get the subject close before you capture it. With digital zoom, your camera uses part of the image and later brings it to the correct size. With
digital zoom, you therefore have more chance of quality loss
.
Do DSLR cameras have optical zoom?
All zoom lenses in film cameras and digital single lens reflex (DSLR) cameras
are optical zoom
. Digital point-and-shoot cameras as well as consumer and prosumer video camcorders have optical zoom, but they also have digital zoom. At the telephoto side of the camera, the computer takes over and interpolates the results.
Do DSLR cameras have digital zoom?

have the possibility of using digital zoom
, depending on the lens you're using.

Despite all the advancements in cameras and digital magnification,
optical zoom is better

What is optical zoom on a digital camera?

a physical camera lens movement
, which changes the apparent closeness of the image subject by increasing the focal length. To zoom in, the lens moves away from the image sensor, and the scene is magnified. It is useful to think of digital zoom as photo-processing software built into your camera.

, and scaling the image up to the dimensions of the original. The camera's optics are not adjusted.
How far can cameras zoom?

IS F 4.0 A large aperture?
A lens that has a maximum aperture of f/1.4 or f/1.8 is considered to be a “fast” lens, because it can pass through more light than, for example, a lens with a “
slow” maximum aperture
of f/4.0. That's why lenses with large apertures usually cost more.
