You view the image through the picture-taking lens on the camera, and it typically has interchangeable lenses capability. Which system is this?

• A. Single Lens Reflex
• B. Rangefinder
• C. Twin-lens reflex
• D. Viewfinder camera

Answer: (A)

Seeing through the taking lens with the ability to swap lenses points to the Single Lens Reflex system. In an SLR, the light passes through one lens, and a mirror above the reflex mirror flips up to direct that exact view to the viewfinder so you compose and focus the shot exactly as the sensor or film will capture it. The interchangeable lenses part lets you use different focal lengths while keeping the same camera body. Other systems use different setups: a rangefinder shows through a separate finder that isn’t the taking lens; a twin-lens reflex uses a second lens for viewing from above; and a viewfinder camera typically has a fixed lens with a separate, non-through-the-lens finder.
