Nothing dramatic, not even a game changer, in this thread l mean but got my little DP4 mount, undid the micro screw, popped it out and screwed it back up on supplied M5 mount, trouble is, it was just hanging there, just, so went to my local "bolt & screw" guy and picked this up, a bolt and a spring washer..l lashed out and bought 6 of them...cause i can - for total of $2... hahah love my work
