Total score ? (maximal 570) | 348 | 348 |
| Pros | + Very sharp
| + Many manual controls
|
| Cons | - Colorful factory settings cannot be modified
| - small wide angle
|
| Conclusion | In terms of sharpness the camera operates at the resolution limit and the available manual control should also be sufficient for many ambitious filmmakers.In addition there are nice innovations such as the short 4K-recording or the automatic recording.Unfortunately the low-light performance is not quite on par with the competition and the partially extreme factory color settings can´t be modified in manual mode. | The sharpness is only slightly below what is possible in this price range and the options for manual control are also quite ok.The touchscreen is a real improvement, so the problems with focus setting we used to citizise are gone.Since Sony offers more manual in this price range than they did before and both Sony and Panasonic have more wide angle, the HF S models of 2010 appear a little overpriced. |
