Now batteries in and turn on. Very homogeneous and uniform light output which practical way can be adjusted even in the intensity and in all modes. So whether the left light right light, ring light, continuous light or flash.
Practically, the LED indicator on the back, where you can see which mode is set, and with what intensity you just photographed.
For product photography required for me this ring light is perfect, but also makes other macro shots his advantage visible. Light without shadow.
The accompanying adapters have been tested by me on SLR Olympus and Nikon and fit properly. The ring light verabeitet the flash signal without any problems and in synchronization with the shutter.
Of course there are clearly better equipment with higher light output for Potraitfotografie but these are also more expensive, but for recording up to 1 meter distance, it is absolutely sufficient. However, the best results can be found at a distance up to 0.5 meters instead ..
The best location is the ring light for well-lit product photos for catalogs or online shops and for Macro Photography.
Conclusion: It does what it should do and really good for this price.
