I had first a different, much more frequently sold and cheaper adapter purchased (MSA-2), in which, however, two problems have been encountered: (1) He was so great that he with difficulty on Sony camcorder CX570E in the AIS shoe could be used and (2) the cover flap for the AIS shoe stuck out in an annoying when holding the camcorder angle. The here now rated AIS adapter is extremely compact, so that the problem does not occur with the projecting cover flap, moreover, the insertion of the metal foot is much easier and safer than with a plastic base possible. To introduce the video light in the base of the adapter, I have a lot of power and ultimately a pipe wrench needed for the adapter is now also extremely firmly to the video light, from which it also does not need to be separated to happiness.
