Query: Love it!

Well, I'm going to have to bunk on the previous reviewer. I love my ZR45MC and have for about 10 years. Have not noticed the humm mentioned, however, will admit sound pretty much stinks; internal mic picks up too much background noise. That said, picture quality is fab. I use mine mostly for scenics, not talking heads, so a music track takes care of the noise. Interface with my Mac is on a kindergarten level. Plug it into the computer, the software starts and the computer asks if you want to download clips.Today I am looking for an external mic to see if I can solve the noise issue. Otherwise, can't think of a reason to get a different camera.
