Don't hang your Nikon with one of those silly bottom straps

Bob I don't know how Nikon does it, but some tripod sockets are nothing but thin stamped steel inserts that are attached to the bottom with two tiny screws. I can say that with the MB-D10 battery grip, the tripod socket is internally supported with a metal plate which runs the entire width of the battery chamber. After 3+ years of abuse I see no evidence of deformation. As far as how the tripod socket is mounted in the D300S camera body goes, i can only guess that it is tapped into the alloy frame, or on a mounting plate attached to the frame, and not just attached with two tiny screws. I would hope the same applies to the D800. -- Regards, Savageduck |

You camera spins around like a watch on a chain. http://forums.dpreview.com/forums/post/50315414 There has to be more to this story. I have been using a BlackRapid strap since 2009 with a D300+MB-D10 and a D300S+MB-D10. I have never had this sort of issue. In my case the BlackRapid strap is attached to the MB-D10 not the camera. However I have no doubt that the D300S frame, or tripod socket bottom plate, would not be damaged in the way described above. As far as being the "One of the silliest accessories ever invented." I consider it one of the greatest. The weight of a D300S+MB-D10 (probably more weight there than a D600 or D800 without battery grip) on a standard neck strap is literally "a pain in the neck". When the camera isn't up at my eye it is at my hip, but I always find myself holding the grip ready to swing it back into action. For whatever reason I very seldom let it swing free as I always take into account the possibility of impact with a stationary object. The BlackRapid strap has made a day out shooting pleasurable, and I don't have that ache in my neck and back that was always there when using a neck strap. I believe we have at least one other BR strap user in these photo-groups, PeterN, there are probably others. ...and I still believe the guy with the damaged D800 in the dpforums story hasn't told all. I just checked the interior of my MB-D10 and there is a metal plate supporting the tripod mount. I do not know the type of metal, but I suspect that it is some sort of steel alloy. The BlackRapid strap has been in constant use on this D300S + MB-D10 since January 2010. I detect no distortion of any type. Here is a quick snapshot (a mite bit fuzzy) of that interior of the MB-D10, where you can see the mount and reinforcing plate. https://dl.dropbox.com/u/1295663/Fil...B-interior.JPG I have pulled the bum out of an F5 which was mounted on a tripod and broken a strap lug attachment point out of the F4 body (80-200 2.8 attached) I stopped using battery bases on my D200 - became unreliable as it distorted from tripod mounting. Camera bodies ain't made to accommodate all things attached |

Last Sunday, I attached the BR to the strap lug of the 800, because I forgot to attach the holding screw. My guess is that since I attached the BR to the loop of the camera strap, over time the strap will become worn. I am looking for other devices after reading that thread. FWIW, I've been using one mostly on my bare D200, but occasionally on my bare D300 with no such issues. I'm not in love with it as much as you are as I believe it allows the camera to bounce too much too easily. This type of loading will cause an amplification of the forces compared to static loading.But so far the tradeoff in terms of ease/speed of getting the camera into position to shoot has outweighed this negative for me with the 18-200mm attached. -- Peter |

Attaching the BR to the Nikon strap lug is probably going to be even more risky than using it attached to the tripod mount. Consider that the strap lug was designed to have the weight distributed over TWO lugs not one, and it was designed to be stressed in one direction. It was never intended to have the full weight of the camera pulling directly against the small thread of the strap lug, which when used with the standard strap has no pulling or extracting force applied. All force is perpendicular to the thread, not in line with the thread. You are likely to cause far more serious damage than by using the BR as designed. Look at it yourself and think it through. If you are wary about using the BR, then revert to the standard strap, don't use a single strap lug which was never meant to take that sort of load. I suggest that you remove the BR from the strap lug ASAP!! Personally I am continuing to use the BR, on my D300S attached to the tripod mount on the MB-D10. -- Regards, Savageduck |

However, I am looking at alternatives. There is a setup involving twin holsters, that sit on your waist. The cameras are also secured with over the shoulder straps. Peter |

Except, pure tension is the most benign loading condition a threaded fastener will experience. |
