Markertek appears to sell one: Part# XLF-H8-10 $49.95
"TecNec Pro XLR Mic To 3.5mm Mini Cables for DV Cameras"
"TecNec's exclusive mic cable design with on-board electronics
allows prosumer camcorders to interface with professional
microphones. Blocking capacitors built into the cable eliminate
the 6-volt DC found on camcorder mic input jacks, eliminating
hum. Built with Neutrik XLR connectors and TecNec Mic-BC
shielded audio cable. 10 foot length."
They appear to be charging ~$40 extra to install a DC-blocking
capacitor in an otherwise conventional cable. But it must be
a REALLY GOOD capacitor! :-)
OTOH, my web page appears to be pretty popular for DIY...http://www.rcrowley.com/CamAdapt.htm
