All user reviews of 4/5 for the Sony PCM-D50

I use this little machine is only for atmospheres in A / B, out crowd, nature, transport ... is behind a spare SD 302 in the output line of the 302-12dB.
Weaknesses: connector 3.5mm line in, which sometimes branlouille and can generate noise (with a rubber band to ensure, for example). Of course the microphones do not sound like Schoeps, but they work honorably for the price.
Strengths: the rotary volume knob, if you have the light fingers can handle without generating noise. The autonomy very comfortable, the use of batteries and battery not dedicated, pre-rec 5 seconds, the robustness of manufacturing.
ABSOLUTELY put on an old pickups down a girlfriend for indoor use, and a windshield pile outside. These are electret and they are extremely sensitive to wind.
Also invest in the remote control which triggers without touching the housing, and possibly a small table leg to move it away from the surface.
This is a simple and practical little machine that follows me everywhere in my shoots over two years. And for now, this is happiness!
