How far can a telephoto lens zoom?

A telephoto lens will let you do it. The distances between the landscape, cityscape, and museum feel much greater at 35mm than at 289mm.

Considering this, what is the zoom of a 300mm lens?

Here is an example: For a 300mm lens, divide 300 by 50 to get 6x magnification. Or divide 300 by 100 to get 3, then multiply 3 x 2 to get 6x. Another example: For a 100mm lens, divide 100mm by 100 to get 1.

Also, what size telephoto lens do I need? What they are: Telephoto lenses are those with a focal length in excess of 70 mm, though many people would argue that "true" telephoto lenses are ones which exceed 135 mm. They focus on a much narrower field of view than other lenses, which means they are good for focusing in on specific details or distant subjects.

Subsequently, one may also ask, is a telephoto lens a zoom lens?

The term "telephoto lens" has a particular technical meaning in terms of lens design, but in common usage it refers to a lens with a long focal length. A zoom lens could "zoom" from a short (wide-angle) to long ("telephoto") focal length, making things look bigger and closer as you zoom in.

What is the difference between a 200mm and 300mm lens?

The difference is one-third of the field of view in linear terms. If a 200mm lens has a field of view of 6 x 9 feet at a certain distance, a 300mm lens will have a field of view of 4 x 6 feet, on the same camera at the same distance. I personally don't notice much difference between 200mm and 300mm when shooting.

How can you tell how much zoom a lens has?

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.

How far does a 50mm lens zoom?

For 35mm or full frame DSLRs, a normal lens is considered 50mm. This yields a very slight magnification, but is basically the same as how our eyes see.
