Total score ? (maximal 570) | 354 | 320 |
| Pros | -Sharpness -Good low light behavior - External buttons for focus, shutter, aperture + custom key
| + Acceptable wide-angle + Good lowlight characteristics
|
| Cons | - small wide-angle - strong, non-adjustable colors
| - No FullHD -3CCDs with pixelshif do not result in full sharpness - MiniDVD
|
| Conclusion | 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. | The MiniDVD as a recording medium does not strike us as particularly useful for HD , so the similar model SD1 is much more interesting. |
