Now say the least HAMA not my 1st choice, but sometimes it reaches a compromise. To the accessory shoe (now there are 5) to make Canon-compatible, I have set (more than in the original 0,1mmm) according to the dimensions of the Canon flash foot a hole of 2.3 mm. For the rich depth less than 6 mm. So I can lock the flash as well as at the feet of the lightning beilegten Canon system flashes. Additionally, I have laterally introduced a 3 mm thread with a stud bolt on accessory shoe. So I can lock the accessory shoe on the threaded stem of the respective holder, so that the flash can not become self-employed in layers. I have to say in fairness that I have both the skills and the opportunities to carry out such work. On bourgeois living room table is not such a thing certainly. In principle, one would ask such reworking to the producer. I forgive also just four points. ---------- Addendum: To my regret, I had overlooked in my above description that the thickness of the leading edge may be different from one article to. In the original Canon-part, the thickness is 1.2 mm, in other, eg Hama 1.4mm. So that the locking lever of the flash unit can be completely folded, so must be filed or sanded 0.2mm. I have done this with the drill press. The slip-clamped with a 1/4 "threaded stud, and ground with sandpaper on a small directional pad to 1.2 mm thickness.
