Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'линза' (correct translation).
- Avoid translating the metaphorical 'lens' as 'объектив' (which is specifically a camera lens). 'Perspective' or 'точка зрения' is better for the metaphor.
- Remember the plural is 'lenses' /ˈlenzɪz/, not 'lens'.
Common Mistakes
- Incorrect plural: 'lens' -> 'lenses' (not 'lenss' or 'lensies').
- Misspelling: 'lense' (incorrect, the correct spelling is 'lens' even for the singular).
- Confusing 'lens' (noun) with 'lends' (verb).

FAQ
Frequently Asked Questions
The only correct plural form is 'lenses' (/ˈlenzɪz/). 'Lens' is never used as a plural.
No. The correct spelling for both singular and as the base of the plural is 'lens'. 'Lense' is a common misspelling.
Yes, but it is specialised. It means 'to film or photograph something', primarily used in the film and photography industries (e.g., 'the movie was lensed in Iceland').
In precise technical optics (e.g., microscopes), an 'objective lens' or 'objective' is the primary light-gathering lens closest to the object. In photography, 'lens' is the general term for the entire device, while 'objective' is rarely used outside technical specifications.
