Using Catia (Mechanical engineering software), I tried to answer your question using retro engineering. First, I took a model of a "random" lens from grabcad.com to get a model of the lens mount. I compared its dimensions to the ones of my lenses and found it accurate enough. On the following view, you can see the lens mount. I used brass as a material ...

It's not just the weight of the camera that's a concern, but the torque that it will apply to the mounting ring on the lens (and in the camera, of course). Torque is turning force, and it's calculated by multiplying force (weight, in this case) by distance from the center of rotation. So, if we guess that your camera is 4" deep from the mount to the back of ...

The 1D Mark II was 55.5 oz. The 5D Mark III + BG-E11 grip + 2 LP-E6N batteries is about 59 oz. The heaviest flash Canon has sold in the recent past is the 600EX-RT which is 18.5 oz with batteries installed. The WFT-E8A is another 1.35 oz. Add that up and you're at 79 oz. which is about 17 oz. less than a 6 pound CCD camera. The EF mount should be able to ...

I don't have the answer for you but the answer is maybe obvious : if it were a classic mechanical problem, I would say that the lens capacity shouldn't exceed the capacity of the body (using no lens collar): If you body can support a 2 kg lens on the body mount, then the same weight is supported by the lens mount ; If your lens comes with a collar for your ...

In my opinion, that ballhead is too lightweight for uses beyond holding smaller DSLRs with shorter/lighter lenses. Many tripod and ballhead manufacturers overstate their "rated" weight. For instance, the Sirui C-10X says it has a capacity of 28.7 lbs. But what is that, in photographic equipment terms? A Nikon D810 weighs 1.98 lb (990 g). With a 600 mm ƒ/4G ...

It depends how the head is made. Most ball-heads move a little which is called drift. A millimeter or two is common but should not be more for anything reasonable. Otherwise it makes framing rather hard. Certain ball-heads are designed specifically to prevent this and are called non-drift heads. Manfrotto for example has a Hydrostatic series like that. The ...

The Sirui C-10X ballhead has a capacity of 28.7 lb, about 13 kg (source : http://mob.sirui-photo.com/productseries.php?productclassid=28). Your Nikon 300mm f4 AF weights about 1.3 kg and a regular camera body is about 1 kg (1.2 kg top for Nikon D3x : https://en.wikipedia.org/wiki/Comparison_of_Nikon_DSLR_cameras) so the total weight your ball has to carry ...
