| 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. | In terms of sharpness the camera operates at the resolution limit and the available manual control should also be sufficient for many ambitious filmmakers.In addition there are nice innovations such as the short 4K-recording or the automatic recording.Unfortunately the low-light performance is not quite on par with the competition and the partially extreme factory color settings can´t be modified in manual mode. |
