Yes i am an amateur videographer.
Shoot video for personal use but like to made all professional. Thats why to have a sound engineer is not my way.
Preffer to be a man-orchestra - its very interesting
(as for my main job - i am a professional photographer)
Yes i understood your joke about 3000 USD microphones
You are right - its true.
This expression "3000 USD guitar sounds like a 300 USD guitar" is a kind of meme on russian-language audio-forums (eastern Europe) and first of time was written by one famous (local) sound engineer about ZOOM (H-series) audiorecorders comparative to another brands with better internal mics sound.
"Zoom is a great recorder, but it makes a 3000 USD guitar to sound like a 300 USD".
Why i ask about D100 alternative - D100 is a kind of "best internal mic sound" audiorecorder.
By the way - i am happy with my M10 and D10.
In any case thanks to all for answers.
