Pros + Lowlight
+ wide angle
+ Many manual controls
+ two formats (AVCHD and MPEG2)
+ good image and lowlight quality
Cons - few manual control options
- Complicated operation
- the controls are hard to getting used to
- formats are not arbitrarily mixable
Conclusion The JVC GZ-HM960 is a very sharp camera with a solid technical foundation, but unfortunately it doesn´t recommend itself for ambitious videographers.Too little manual control is offered along with the otherwise very up-to-date technical specs.Rather, the GZ-HM960 will appeal to users who are interested in technical gadgets.The 3D mode, however, is no comparison to real 3D camcorders and should be seen more as a gimmick.The similarly constructed but cheaper GZ-HM845 on the other hand, would be a pretty interesting device in its price class, if only JVC would have enabled more manual features.In its 1000 Euro price class the competition by now allows more manual control.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.
