Meaning

Linguistics
Semantic Notes
Often abbreviated to 'TLR'. The term is strongly linked to specific, now mostly vintage, camera models (e.g., Rolleiflex, Mamiya C series). It is a sub-type of reflex camera, distinct from the single-lens reflex (SLR).

FAQ
Frequently Asked Questions
No. An SLR (Single-Lens Reflex) uses one lens for both viewing and taking the photo. A TLR (Twin-Lens Reflex) uses two separate, matched lenses.
The rise of more versatile SLRs and later digital cameras made TLRs, with their fixed parallax error and generally non-interchangeable viewing lens, less practical for most applications.
It refers to a mirror ('reflex' mirror) inside the camera that reflects the image from the viewing lens up to the ground glass viewfinder, allowing the photographer to see what the lens sees.
Very few are made new today (e.g., some Lomography models). They are primarily sought after as collectible vintage or film photography tools.
