I just received this superlight unit from B&H, at $60 regular price.
It’s powered from the camera or other 3 v supply, and has no internal battery requiring periodic checking and replacement. I use another mic of similar size and weight of Chinese origin (see my equipment list page), which uses an internal CR2 battery; both have their advantages re powering. This microphone really is to be used by direct connection to a camera’s 3.5mm jack.
This type of mic is very useful for a number of situations: vehicle interior audio, backpacking, minimalist travel/photojournalism, creating tutorials at the computer screen by reversing the mic on the camera’s hot shoe for voiceovers… the excellent Rycote windscreen allows realistic use in moderate wind conditions.
It also has a 3/8″ base thread for use with a standard boompole.
Be sure that NO PHANTOM POWER is applied to this unit!! If employed with a Zoom H6, using plug-in power = 2.5 v for that particular recorder, be sure to set up for plug-in power before connecting the microphone. Set the Tascam DR-70 D digital audio recorder to EXT POWER to enable plug-in power.
My preliminary assessment of sound quality is that I would happily use it with an NTG-4 or Audio Technica Pro70 wired lav mic. Gain is more than adequate.
The fact that it has no controls whatsoever contributes to a streamlined, simple form factor; when I need to control the width of pickup coverage, I ‘d go to the Shenggu SG-180 shotgun (90-120 degree settings).
