wide-angle converter
C2Technical (photography, videography)
Definition
Meaning
A lens attachment that widens the field of view captured by a camera lens, effectively reducing the focal length.
A supplementary optical element (or adapter) that screws onto or mounts in front of a camera's primary lens to allow it to capture a broader scene without changing the camera body. In a more figurative sense, it can occasionally describe a method or tool that broadens one's perspective.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'широко-угловой конвертер'. The standard Russian term is 'широкоугольный адаптер' or 'насадка для широкого угла'. 'Конвертер' in Russian tech contexts more often refers to a signal or data converter.
- Do not confuse with 'широкоугольный объектив' (wide-angle lens), which is a primary lens, not an attachment.
Common Mistakes
- Using 'wide-angle converter' to refer to a built-in wide-angle lens on a camera or phone. It is an add-on accessory. / Saying 'wide converter' (ambiguous). / Incorrect plural: 'wide-angles converters' (correct: 'wide-angle converters').

FAQ
Frequently Asked Questions
No. A wide-angle lens is a primary, standalone lens. A wide-angle converter is a secondary accessory that attaches to a primary lens to modify its field of view.
It can, especially with lower-quality converters. They may introduce optical aberrations like vignetting (darkened corners), chromatic aberration, or softness at the edges. High-quality models minimise these effects.
No. They are designed with specific filter thread sizes (e.g., 52mm, 67mm) or lens mounts. You must ensure the converter's thread size matches your lens's filter thread or that it's compatible with your lens system.
A telephoto converter (or teleconverter), which increases the effective focal length, magnifying the subject and narrowing the field of view.
