Pros + Lowlight
+ wide angle
+ manual controls for shutter and aperture
+ factory setting adjustable
Cons - few manual control options
- Complicated operation
- somewhat blurred compared with other HD video
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.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.
