Answer 1

Common features of DSLR cameras include interchangeable lenses and a mirror system for viewing through the lens; they also tend to include optical zoom and have a higher cost compared to point-and-shoot cameras. The correct option is D.

Step-by-step explanation:

The features common in DSLR cameras are that they often allow for interchangeable lenses and usually have a mirror that allows the photographer to look directly through the lens, which is part of what distinguishes them from other camera types like point-and-shoot cameras or smartphone cameras.

DSLRs utilize complex lens systems for superior image quality, and the optics involved are based on the principles of basic optics. The camera's lens system, akin to a single lens with an object distance much larger than the lens's focal distance, works to produce clear images with minimal aberration. Additionally, DSLRs are known for their capabilities in optical zoom, unlike digital zoom which simply enlarges the pixels, resulting in a potential loss of image clarity.

Contrary to one of the options provided, DSLRs often do include optical zoom and are generally more expensive than point-and-shoot cameras due to their advanced features and image quality.
