Summary: I'm not an expert on digital video cameras - I mainly use this as a playback deck for transferring film footage to the computer. However, I find the picture bright and colorful compared to my old canon z10, which recently broke. The firewire connection to my mac is reliable as well. I don't know how this compares to more professional cameras, but it seems to be a great camera so far and I'm happy with the purchase.
Summary: The main reasons I bought this (now discontinued) model are: it has 3 ccd chips (great for color and detail, especially outdoors), it's size and feel, and the fact that it has an accessory shoe and mic input. I use it for family videos, and for short videos for our church's youth group. The clarity is great, and the sound is good for such a small camcorder. The backlight compensation feature works great!
Summary: I bought the GS180 prior to my trip to China. I also bought a 4 hour after-market battery; I've since bought another one. That's what you'll need if you are touring all day and using the LCD screen all of the time. With the battery, the viewfinder becomes just about useless since it doesn't tilt up. Another review says that the camera doesn't come with a lens cap; mine did. I've had a remote for my Sony Digial 8 but have only used it a few times.
Summary: It's a great, light little camera. Very handy for field work. I'm very pleased with it. it can take still photos. I find the USB 2.0 video transfer very useful: saves me the trouble of buying and installing a firewire card. It does not get the full 5 stars because, unlike many, if not all, the previus models of the same line, it DOES NOT include the hand remote control. Too bad, because it woould have been a mayor bonus.
