This bracket has found itself collecting dust instead of living in my camera bag for some time. While it does collapse well, in a reasonably sturdy mechanism, it's still a pretty bulky unit. Sadly, the basic makeup of this bracket isn't strong enough to hold a full-size flash (580EX) safely in one place, making it totally useless (for me).

My opinion on DealExtreme is the best because it is a transparent company that serves its customers from a distance, as in my case I'm from Brazil.

Tous, me direz-vous? non, pas tous: Nikon a en effet un tirage optique plus grand que les autres, et que le M42 en particulier, ce qui fait que si vous montez du M42 sur du Nikon, bye-bye la mise au point à l'infini.
