Total score ? (maximal 570) | 367 | 354 |
| Pros | + Many manual controls
| -Sharpness -Good low light behavior - External buttons for focus, shutter, aperture + custom key
|
| Cons | - fiddly operation - No Zebra - Manual focus very poor
| - small wide-angle - strong, non-adjustable colors
|
| Conclusion | 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. | 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. |
