Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'автоматический фокус' in non-technical metaphors; use 'автофокус' for cameras. In metaphorical use, 'automatic focus' does not translate directly; instead use phrases like 'саморегулирующееся внимание' or 'автоматическая концентрация' depending on context.
Common Mistakes
- Using 'automated focus' (less idiomatic). Treating it as an uncountable noun (*'much automatic focus'). Confusing it with 'auto exposure'. Using it as a verb (*'The camera automatic focuses').
