Total score ? (maximal 570) | 342 | 293 |
| Pros | + Many manual controls + two formats (AVCHD and MPEG2) + good image and lowlight quality
| + manual controls for shutter and aperture + factory setting adjustable
|
| Cons | - the controls are hard to getting used to - formats are not arbitrarily mixable
| - somewhat blurred compared with other HD video
|
| Conclusion | The possibility to record both HD-consumer formats is a good thing, but some details are missing (the formats can not be combined at playback, no backup-tape, no HDV-recording on SD cards).Nice to see that with this introduction of CMOS sensors JVC closed the gap of lagging behind in picture qualityMany important parameters can be adjusted manually, which is great, but the operation requires a little too much patience and practice.If JVC would have included the rich manual controls of the HD7 this cam would have been a real winner for every ambitioned movie maker. | This cam shines with unusual (in this price category) manual controls and smart automatic modes and a touchscreen.But the small 1 chip sensor limits the picture quality too much. |
