Total score ? (maximal 570) | 350 | 276 |
| Pros | + Many manual controls + two formats (AVCHD and MPEG2) + good image and lowlight quality
| |
| Cons | - the controls are hard to getting used to - formats are not arbitrarily mixable
| |
| 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. | No focus ring, no manual controls, no viewfinder, no audio connections, and crippled manual values are inaccessibly hidden in colorful menus.Analog output is NTSC-only, and a new video format is used that is even worse to edit than AVCHD.The sharpness is achieved through extreme contourCompared to Sony, Panasonic and Canon the codec shows even more artifacts. |
