How far can a 800mm lens zoom?

⁠⁠⁠⁠⁠⁠⁠

A 800mm lens can zoom a long ways. Depending on the make and model of the lens, a 800mm lens can zoom in on objects from a few feet away to several miles away. Some 800mm lenses even have a zoom range of up to 24x, which means that the lens can zoom in on an object up to 24 times its original size.

While a 800mm lens can provide some amazing zoom capabilities, it’s important to note that the lens’s zoom range will vary depending on the camera it is attached to. For example, a 800mm lens attached to a digital SLR camera will have a much greater zoom range than a 800mm lens attached to a point-and-shoot camera. So, if you are looking to purchase a 800mm lens, be sure to check the specifications to see how far the lens can zoom in on objects.

In addition to its zoom range, it’s important to consider a lens’s aperture when determining how far it can zoom in on an object. The aperture is the opening in the lens that allows light to enter the camera. The larger the aperture, the more light the lens can capture, which in turn allows the lens to zoom in on objects farther away. So, if you are looking for a lens that can zoom in on objects from a great distance, be sure to check the aperture size as well.

All in all, a 800mm lens can provide some amazing zoom capabilities, depending on the make and model of the lens. So, if you are looking for a lens with a lot of zoom, a 800mm lens may be a good option for you.
