+ Many manual controls
Cons - few manual control options
- Complicated operation
- fiddly operation
- No Zebra
- Manual focus very poor
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.Compared with the older models of the same series the smaller sensor, the picture problems and the exaggerated sharpness offer no real advancementsAdd to that the bad low-light sensitivity with some bright pixel noise, the missing histogram and zebra-displays and the manual focus problems.On the positive side: the low price and the fact that the pictures in the automatic mode (assumed there is enough light) are sharp and generally good.
