Summary: I've had this camera for a while now (mostly used for family events), but will start shooting web videos with it in a few weeks. It is worth noting if you are looking to buy a stedicam for it (like the flycam) pay no attention to the Panasonic website or literature that pegs the camera's weight at a paltry 1 lb. According to my scale -- the camera weighs at least 13 lbs. With battery we're talking 12 - 15 lbs. CNET's review seems to agree with my scale.
Summary: I like that it has no hard drive and does 60fps 1080p. The video quality of this camera is just incredible. I love the HD this camera records and I am picky. Glad I went HD to record those moments forever and watch them in their glory on my 64" Sony HDTV. Photos in good light look great, but low lighting produces purple tone to image and is a bit blurry, but hey I bought it for its video not photos. Image stabilization works great, best I have had on a Camera.
Summary: I'm not a prof. videographer by any means. Coming from using a Sony Mini-DVD camcorder from about 3.5 years ago, this is a fantastic upgrade! With that disclosure, I'm very happy with it so far. The clarity is amazing and general ease of use is great. I haven't tried taking any photos, so I have no comment on that functionality. I'll focus my feedback on the Apple Mac issue.
Summary: I've been out of the camcorder game for some time so my view of a great camcorder may be a bit skewed, the image quality on IA mode and 1080/60p is quite good, and plays back very well on an HDTV. I had no issues importing the videos to Adobe Premiere Pro CS5.5 for editing and compilation. The controls are fairly easy to navigate and the touchscreen is responsive and easy to use, the included stylus is helpful but not necessary.
Summary: The Quality of the picture is excellent. My Largest disappointment was that there is no audio input, so I can connect my wireless microphone to the camera. I will have to record to an audio recording device and then go to all the bother of synching the audio and video in post production. Other wise there is all that ambient and unwanted sound. The person talking in the back row, the coughing. most of which cannot be easily removed.
Summary: I have worked in television for 21 years and now produce video for a public agency. I purchased the HDC-SD800 because Panasonic eliminated all the useless frills on the higher-priced models. This camera has the same lens, MOS chip, and useful features needed, but at a much lower price. BUT OOPS.....! Even at this writing Amazon advertises this camera as a "Twin Chip" camera. Sorry, not so! There is only one chip slot on the camera.
Summary: I had been waiting a long time to find a camera with high visual fidelity without all of the consumer oriented junk that comes with most home cameras, and this is it. I will go from the most annoying problems/features, and move up from there. Color Quality: The 3 CMOS sensors (3MOS they call it) does an excellent job at color accuracy.
