In terms of focusing, what makes a standard lens different from a telephoto lens?

The distinction between standard lenses and telephoto lenses is primarily influenced by their field of view and focal length. A standard lens, often designed to approximate the perspective of the human eye, typically has a moderate focal length (around 35mm to 50mm on a full-frame camera). This focal length allows for a broader field of view, making it suitable for capturing wider scenes without significant distortion.

In contrast, telephoto lenses have a much longer focal length, which narrows their field of view and allows them to magnify distant subjects. While telephoto lenses can capture images from far away, standard lenses focus more on composition and context, offering a wider perspective better suited for capturing groups of people, landscapes, or large subjects. This characteristic makes standard lenses beneficial for a variety of general photography situations.
