The lac mic is not the problem, bad placement is
The tiny mic in hand thing does not bother me that much. For quick interviews, social clips, BTS stuff, etc., I get why people do it. A visible mic has basically become a visual cue for "casual or real person talking", even if it looks a little silly.
What does bother me is when people copy the look and forget the actual audio part. Holding a lav close to your mouth for a short clip is one thing. Holding it at other body level in an outdoor interview and expecting clean dialogue is just bad placement.
Small wireless mics made audio look too easy. Distance still matters. Wind still matters. Clothing noise still matters. It is still a microphone, not a magic sound button.
So I do not think visible lavs are automatically amateur. But using one as a prop and forgetting proximity definitely is.
For short social or client content, are you hiding lavs every time, or are visible tiny mics just pat of the look now?
