This K&F Concept Camera Microphone comes presentably boxed and in the package apart from the microphone you get a foam windshield, CR2032 button cell and a decent set of illustrated instructions. We used this microphone with a Nikon D7200 DSLR on a recent trip to photograph some Kingfishers. The microphone has a claimed frequency response of 50Hz to 16KHz and an impedance of 200 Ohms.The immediate impression is of good quality product which is largely of metal construction. This mono microphone is powered by a CR2032 which should last 50-60 hours before an LED indicator flashes to warn of a low battery condition. The battery is easily fitted by opening a screwed door at the rear of the microphone. There's a short 3.5mm audio lead which plugs into the camera and the microphone is easily fitted to the camera via the integral hot shoe mount. The only control is an on/off switch which can also enhance the sensitivity by 10db. I personally prefer to use the microphone with the foam windshield on.In the field we found this microphone performed well. There was very little mechanical noise from the camera and although wind noise was kept to a minimum plenty of both foreground and background detail was captured including birdsong. The sensitivity enhancement switch produced a noticeable effect albeit at the obvious expense of slightly more noise. Because of its light weight this is an easy microphone to manage too. Overall we are delighted with the audio quality captured by this microphone and would unhesitatingly recommended it as good value solution for a DSLR or camcorder user. Recommended.(Disclosure: I was provided with a free sample for review - the opinion above is my honest view of the product).
