Summary: Bought in 2002, great camera until two weeks ago. When I rewind the dispay on LCD reads Eject Tape, I remove and re-insert until I get rewinded. I see from reading about this camera that this is a common problem. Just wait..
Summary: 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.
Summary: Giving my unbiased opinion: I am an adult and i know my way around technology. I owned other canon products before from powershot cameras to this ZR45MC. I've had this since early 2002 and I've used it for many things, graduations etc.... I just recently had problems.
Summary: This was my first digital camera, and I absolutely love it. Still going strong after 4 years. I've used it on trips, to record concerts, and just general fun. It's incredibly easy to use. The complaints I have are geared towards the fact that it's outdated.
Summary: one thing to watch out for,when using the zoom button,dont just let it go after you zoom,or it will click and the noise will be recorded. however,if you edit and can dub different audio then it wont matter. that said, we love the camera.
Summary: It was a pretty good camera until it stopped working. One day I turned it on and it started beeping and flasshing an eject tape message. But you couldn't eject the tape and the camera would not respond to anything. I had the camera just over two years when this happened.
Summary: As with others, this was a great camera until the remove cassette problem appeared 8 months ago. Now it barely plays or records. I'm never buying another Canon and going back to Sony. BTW, the buzzing is the automatic microphone gain.
