Total score ? (maximal 570) | 412 | 378 |
| Pros | + Sharpness and colour at the upper AVCHD limit + Many manual controls + 1080p50
| + Lowlight + wide angle
|
| Cons | - No Expanded Focus - No touch focus in manual mode
| - few manual control options - Complicated operation
|
| Conclusion | Not only does Panasonic offer 50p, it also brings enough wide angle (which even isn´t affected by the active image stabilisation), good low-light performance and colors, great sharpness and lots of manual control.Also nice is that the 3D features are now offered as an alternative add-on option. | 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. |
