BUT:
The stability is however quite bad, it slips on the flash rum and "bowing to pressure" - with the result that it depends (28cm model) with short lenses front of the lens and thus the image.
Since I need the softbox for portrait photography, I actually in the case always a short fixed focal length off.
Conclusion:
For protablen use, I wanted to cover it, really inappropriate. This record may have the smaller model would work better there.
Away from the camera in the studio quite useful, but I prefer to use umbrellas.
