working on two cameras this small (especially for its size) flash unit without blemish. The automatic functions are implemented exactly as accurate as the manual settings. However, the built-in video light is not convincing. Einzigst at Macro / high Isowerten can be worked with it, but with the entsprchenden noise performance of the sensor. The dials could slightly better grip, but basically okay. The stated energy consumption (at full load about 220 lightning) is coherent. The often criticized plastic flash foot is a two-part shoe - with a metal plate in the back third. This is by design, because Sony has a multifunctional hot shoe on his Alphas. So forward a contact strip. To me, the stability sufficient. Conclusion - the size / quality / performance, there are no alternative and can convince.
