DSLR

Definition

A DSLR, or Digital Single-Lens Reflex camera, is a type of digital camera that combines the optics and mechanisms of a single-lens reflex camera with a digital imaging sensor. This type of camera is known for its versatility, high image quality, and ability to change lenses, making it ideal for various photography styles, including formal headshots and sports photography. The reflex design allows photographers to see exactly what the lens sees, providing accurate framing and focus.
