Total score ? (maximal 570) | 378 | 354 |
| Pros | + Lowlight + wide angle

|
| Cons | - few manual control options - Complicated operation
| - small wide-angle - strong, non-adjustable colors
|
| 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 GZ-HM1 is leading in the race for sharpness in its 1000 Euro range of 2010 camcorders.Also in low light conditions the camera makes a good impression.In spite of its price tag it is not possible to adjust the colors, which is unfortunate because they remain a matter of taste and are sometimes even on the verge of being critical.The external controls will be interesting for people who like to manually adjust things and be in control.In addition to the inertia of the parameters, the user must decide if a fast white balance or the focus aids should be assigned to the custom key.Because for the other it means diving into the menue via laser touch.Also, the small wide angle is not very inspiring. |
