The Sanken CS-M1 is a tiny but mighty supercardioid microphone intended for use on smaller camera rigs or – perhaps more realistically – boomed for recording dialogue or interviews indoors.
It’s only four inches long (about 10cm) and weighs 1.9oz (55g) and the mic’s frequency response of 100 Hz to 18 kHz is claimed to attenuate low frequencies naturally without the use of filters or limiters. A small pop shield (not shown in these pictures) will help to further reduce rogue plosives from your subject.
The Sanken CS-1 is a great alternative on-camera shotgun mic to mainstays like the Sennheiser 416 so I’m sure the CS-M1 will be a solid performer as well. It’s available to order now for around $900 US.
