I videotaped a skating carnival this evening (okay, there was no tape involved - more of that later). But I forgot the cable that attaches the wireless mic receiver to the camera. Fortunately, I had Plan B to fall back on. I simply put my iPod Touch in the M.C.'s pocket with a bit of the headphone cable with the mic sticking out. Then I hit the record button in the Voice Memo app and it worked quite well. I'll sync it later in the computer.
I borrowed a video camera from a friend to record the show and it's really good: a Panasonic HS700 with 240 GB hard drive. Great wide angle lens, excellent image, good low light capability. Read my review here.
