Total score ? (maximal 570) | 367 | 252 |
| Pros | + Many manual controls
| + HDV-compatible disk recording + High color resolution + good manual settings
|
| Cons | - fiddly operation - No Zebra - Manual focus very poor
| - No FullHD - Bad low light performance - small wide angle
|
| 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 JVC GZ-HD7 provides full 1920x1080 pixels for recording, which does not result in a visible improvement in recording quality, though.The recording mode 1440x1080 suffices for a full image performance with a good color resolution.The subjective image impression is satisfactory; when recording images with low contrast the details diminish due to the significant contour.In terms of color the GZ-HD7 is quite rich, the white balance on the other hand is often slow.With little light, the image grows quickly gloomy despite of the three CCDs, which combined with the relatively small wide-angle makes it less suitable for interior shots.Our test pattern also showed significant blurs and aberrations on the right border, which might suggest a not quite correctly built-in lens. |
