How to say "finder" in Japanese

• ファインダーCommon
  nounThe loanword for a camera's viewfinder, the window you look through to frame a shot. This is the everyday word for that photographic sense of 'finder'.
  被写体ひしゃたいに気きづかれないようにそぉっとカメラを取り出とりだし、ファインダーを覗のぞく。↗

  I quietly take out my camera, so as not to be noticed by my photographic subject, and peek through the finder.
• 拾い主ひろいぬし
  nounA person who finds lost property and picks it up. Less common; it emphasizes the finder's relationship to the item found, as when deciding whether to hand it in.
• 拾得者しゅうとくしゃ
  nounAlso a finder of lost property, but less common and more formal-sounding. It is the term you are likeliest to meet in official or legal contexts rather than casual talk.

Use 「ファインダー」 for the optical/electronic viewfinder sense of 'finder'; use 「拾い主」 or 拾得者 only when 'finder' means someone who finds and turns in lost property.
