    Default Shotgun Mics for Olympus Pen


    Hi,
    I've been filming wildlife with an Olympus Pen E-PL1 (connected to a Sigma 500mm lens via an adapter), and getting quite good sound with the Olympus ME51S external microphone. However, I want more directional sound, so tried two shotgun mics - a Hama RMZ-10, and a Sony ECM-CG50. Both gave extremely low volume sound, to the point of being almost inaudible. I tried using a pre-amp, and turning up the gain, which helped a bit, but not enough.
    Anyone used a shotgun mic successfully with my camera (or similar), and which one was it? (I'm a total novice at this as you can no doubt tell.)
    Thanks.

    I use a Zoom H2 as a pre-amp and an Audio-Technia ATR6550 Condenser Shotgun Mic with good results. A wind filter is a must, other wise there will be a lot of wind noise recorded.

    Thanks for the suggestion.
    I was wondering whether any shotgun mics would give good results plugged directly into the EMA-1 mic. adapter (like the ME51S), or whether a pre-amp would likely always be needed with a shotgun mic to boost the volume?

    How far away are the animals? Shotguns are very directional but don't reach extremely far. I have done sound for movies and moving the shotgun back just a few feet can make the audio unusable{and get you yelled at by the sound mixer and maybe the assistant director}. As a general rule the longer the shotgun the longer distance it can pick up but it also tends to pic up a narrower frequency range. Shotgun mics are set for the human range and it could be that the animals are higher/lower in frequency? You might want to check out a parabolic mic{they can be home made!}.

    I suspect that the two microphones that you used need Phantom power to be audible. In other words, they get power from the camera. And I dont think your camera offers that. There are alternatives to this with mics that run on batteries. Some manufacturers run two models on their mics for this reason. I think Rode offers this. We use an NTG series mic on a weekly basis and it offers good results. Audio Technica is known as a good cost efficient brand too.

    I use a Rode (not a shotgun version) with good results, on my GH2

    Gerald has it right. You want a self (battery) powered mic. The camera is not providing enough power to the mics.

    Hi, Appreciate the replies. Both the shotgun mics I have tried are powered by a single AA battery.
    Here's a link to my first effort to film with this camera, using the external Olympus ME51S microphone mounted on the end of the lens, and using a homemade wind muff (the birds are about five to ten metres away):



    The sound is not bad, but I was hoping for something more directional to cut out some of the extraneous noises behind the camera, hence trying a shotgun. As I said, even using an ART pre-amp with the gain turned right up, the volume is still below that of the Olympus mic. Perhaps I might sell the Sony and try with an Audio Technica or Rode. Pity Olympus didn't make a dedicated shotgun mic for the Pen cameras!

    The mics pick up sound from the back almost as much as they do from the front. Generally speaking I run a Rode Video Mic Pro and either run it straight into the camera via the SEMA1 connector if I'm working loose and fast, or if I'm static and using a tripod then I connect the mic via a Zoom H2n recorder this enables me to monitor the levels via screen and headphones.

    Yes, shotgun mics pick up behind them as well as in front! They have a pickup pattern like this.

    This is the reason why they are pointed down when used on a set.


    For the best results for what you are doing I would use a parabolic mic. You can use the shotgun head if the tube will screw off and build your own. They are true uni-directional and have a much longer pickup range than any other mic.
