single-lens reflex camera
Let an agent explain single-lens reflex cameras and how they work, describe film and digital models and formats, support choosing and using them and comparing with mirrorless cameras, and describe their history.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain single-lens reflex cameras and how they work, describe film and digital models and formats, support choosing and using them and comparing with mirrorless cameras, and describe their history.
A camera in which a mirror and prism system lets the photographer view the scene through the taking lens, with the mirror flipping up at exposure to expose film or, in digital single-lens reflex cameras, an image sensor, allowing accurate framing and interchangeable lenses, produced in film and digital forms and in formats from thirty-five millimetre to medium format by manufacturers including Nikon, Canon, Pentax and Hasselblad; the design dominated professional photography for decades and is being succeeded by mirrorless cameras.
What it is for: Cameras with through-the-lens mirror viewing.
It can be explain how they work; describe models and formats; support choice and comparison; describe history.
