My first impression with DR-5 and D700 (after DR-6 and D300) was quite shocky There seemed to be no lock or rotate possibility while attaching this gadget. Ok, my bad and user error as usual. When you attach this thingy into the camera, you can actually rotate the whole thing by using some force to get it properly in level. When in place, it seems quite secure and sturdy -there's no possibility to accidentally drop this one, unlike the DR-6. There's a price you have to pay for bigger VF...the usability in this case, DR-6 was quite handy actually.
