So I am just getting into the wonderful world of field recording. I picked up a PCM-D50 about a week ago and love it. The internal mic's sound great and the pre is nice and smooth, quality converters and headphone amp as well. I am noticing how sensitive the mic's are, they excel in ambiance recording and basically any other recording where outside noise is minimal. However I am considering adding a more directional external mic (mono or stereo) to my aresenal. I don't really want to spend $500 on the XLR phantom power extension for the PCM-D50 so I am wondering what my options are for a shotgun or hypercard mic that has battery powered phantom and a 1/8 inch output? Does anything like this exist? Would be a great companion to the excellent internal mics on the PCM-D50 I feel. Thanks.
