Inside the microphone roars even more strongly, even for lay clearly audible when the internal microphone of the RX100 m2.
I can not use it thus.
To "prove" / test, I made a video by me. The microphone with the internal microphone, the micro of the Nikon D800, the Rode Video Mic Pro compare to the D800, and the field recorder Zoom H1
On YouTube with the keywords "XYST1M" and "Rode" and "RX 100" determined easy to find.
Spoken word, a Field Recorder, which is closer to the sound source, really nice map.
The Rode I feel much more comfortable with the sound and therefore better.
I'm going for interviews always use a field recorder and the sound then on average just need to synchronize after-.
But for 130 I expect more than 10-15% increase in performance.
Am disappointed. If Sony has built a proprietary connector, instead of a jack plug, I expect good accessory.
But this microphone is not really in my opinion better than the internal microphone.
For general photography such as atmosphere, children's videos, or or, you can calmly take the internal microphone.
Either the internal microphone is very good, or the XYSTM1M simply unsatisfactory for my taste.
