reflex camera
C1Technical, Formal, Everyday (among photographers)
Definition
Meaning
A camera that uses a mirror system to allow the photographer to view through the same lens that will take the picture, providing a through-the-lens (TTL) viewfinder.
The term often refers specifically to Single-Lens Reflex (SLR) cameras, both film and digital, which dominate professional and serious amateur photography. Modern usage has shifted somewhat towards 'DSLR' for digital versions, while 'mirrorless' cameras offer a different mechanism for achieving a similar electronic viewfinder result.
Linguistics
Semantic Notes
The 'reflex' refers to the mirror that reflects the image up into the viewfinder, which then flips up ('reflexes') out of the way when the shutter is released. The compound noun is usually hyphenated when used as an adjective before a noun (e.g., 'a reflex-camera system').
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. 'SLR' is the common abbreviated form in both regions.
Connotations
Identical in both regions: suggests technical capability, manual control, and professional or serious amateur use.
Frequency
Equally common in technical and photographic contexts in both regions. In everyday speech, 'digital camera' or just 'camera' is more frequent among non-specialists.

Learning
Memory Aids
Mnemonic
Think of the mirror in the camera REFLECTing the image to your eye, then quickly flexing (reflexing) up and away when you take the shot.
Conceptual Metaphor

- Avoid direct translation like 'рефлекс камера'. The standard Russian term is 'зеркальный фотоаппарат' (literally 'mirror camera') or 'зеркалка' (slang).
Common Mistakes
- Misspelling as 'reflex camera' or 'reflexcamera'.
- Using 'reflex camera' as a general term for any advanced camera, including mirrorless models.
- Confusing 'Single-Lens Reflex (SLR)' with the older 'Twin-Lens Reflex (TLR)' design.

FAQ
Frequently Asked Questions
A DSLR is a type of reflex camera with a mirror that reflects light to an optical viewfinder. A mirrorless camera lacks this mirror, so light hits the image sensor directly, and the viewfinder is an electronic screen.
In modern common usage, yes. 'Single-Lens Reflex (SLR)' is the precise term for the most common type of reflex camera. 'Twin-Lens Reflex (TLR)' is another, older type.
No. While most professional cameras were reflex cameras (DSLRs) for decades, the professional market now includes many high-end mirrorless cameras which do not use a reflex mirror mechanism.
Reasons can include preference for an optical (not electronic) viewfinder, extensive existing collections of compatible lenses, specific ergonomics, or familiarity with the system.
