The quality from this camcorder is amazing. The sharpness and detail which it packs into the video are breath taking. The video format is 24mb/sec AVCHD, the top quality available for this format (except the newly released 28Mb/sec AVCHD2) and it shows. Having said that it does have a lot of quirks. I can understand why, while only being a 3 year old model, it's price has plummeted to about a third of the original cost. It's very very small, which means it's extremely portable but equally hard to hold steady while filming, also due to it's rectangular boxy shape. The poor stabilizer, despite being the upmarket optical type, dosen't offer significant help. And the controls are extremely hard to operate. In auto mode it tends to over expose in bright light, and is extremely poor in low light, both problems stem from the limited aperture range. The X900 does have a comprehensive set of manual controls. Every aspect can be controlled; aperture, shutter, focus, gain and more can all be manually set. But the long winded menus, the touch buttons and 'laser' strip make this an excurciatingly slow and fiddly process. Still, hats off to the manufacturer for allowing these settings to be set individually, as this option is not always present, even on expensive camcorders, Sony being a notable example.
If you do have small steady hands which can hold this camcorder well, and manage to keep it from over exposing (by not filming directly in bright light) it will shoot some of the best quality video you've ever seen. Again, it's small size makes it extremely portable, and the video it produces is head and shoulders above point and shoot cameras, smartphones and other camcorders in its price range. If you can live with its faults, and want a small camcorder the GZ-X900 offers amazing value for money. But if you value useability, ease of use, an auto mode which produces the best video regardless of conditions and amazing stabilization then go for a top-end Sony camcorder, such as the CX700 or CX560. They're expensive but worth every penny! Having bought the GZ-X900, tempted by the low price, I have relegated it to a second camera, filming unattended on a tripod at a wide angle, while I shoot close-ups and details with my Sony XR520. At this price, I certainly do not regret my purchase, even though for me it is unuseable as an everyday camcorder.
