This is a pretty decent, lightweight microphone, suitable for most DSLs and superzoom/bridge cameras that have a standard mic socket.It's got a cardoid response (with a fairly good rejection of sound from behind, but it cannae change the laws of physics). Sound quality is great for the price. Noise isn't overwhelming, as some older reviews say -- I suspect the internal electronics have been upgraded since then.Speaking of which, as a condenser mic, it needs power to drive those internal gubbins. So the package comes with a lithium button cell (not rechargeable). Mine hasn't run out yet, so I can't verify the 50 hour battery-life claim. Replacements are easily available, such as this six-pack, branded Panasonic.Curiously, I see one or two Amazon reviews saying the sound quality is no better than the built-in mics in their cameras. Either their cameras have excellent microphones, or they made the same mistake as I did at first: I failed to push the jack fully home! The Fuji socket is rather stiff, and it's recessed so it's hard to see that the jack isn't properly in.Also, don't forget it's a mono mic. I'd have thought this was obvious, but apparently not so!What would I improve? It would be good to have a low-battery indication. Also some rubber construction between the body and the camera mount might help attenuate the transmitted handling noise when you zoom, focus, etc. Otherwise, this might have got five stars.In case you were wondering, the body is 130 mm long with its foam sock on, and it sits 65 mm above the flash shoe.Unboxing photos attached, plus a photo of it attached to my Fuji X-S1.Full disclosure: I was asked to test this product by K&F/dcmall, but this review is my genuinely independent opinion.
