Just ordered a Benro Gimbal head for my tripod. Now the head comes with the PL-100 release bracket and i have also purchased a PL-85 release bracket as well.My two biggest lenses i shall be using it with will be the Nikon 500AFS and the Sigma 120-300 f2.8.

On the Benro site it says the PL-85 is suitable for the 500 AFI but when i measure the 500AFS foot it is longer and is actually longer than the PL-100( this is the one i planned to use for the 500AFS i have ) size which the Benro site says is for the 600AFS.

Anyone else use the PL-100 or PL-85 feet with their Benro Gimbal head and if so which lens do you use them with. I just assumed the Benro release bracket should be slightly longer than the foot it being placed on--is this correct.

ps- My 500AFS actually has a Kirk LP47 foot on it just now so that may be longer than the Nikon version.
 
The only reason you tend to need a long foot with big lenses is so that you can adjust the balance point, depending on the weight of the camera, by sliding it fore and aft. So long as you can achieve balance, the overall length doesn't matter.

Actually, the closer the balance point is to the fixing bush itself, the more rigid it will be - in theory at least, not sure it makes any odds in practise. In which case you could get away with a very short plate.

Thanks for the reply.I will wait and see how it goes when they arrive but talking to another member he says the PL-100 is huge and will be fine. The Sigma 120-300 has a small foot so the PL-85 is earmarked for that when i get it.

It is exactly 100mm long :thinking:

Forgot to say that with a big lens the most important thing is to make sure the little locating lugs at the back of the plate are butted up to the lens' foot. Stops it rotating if you use a side mounted gimbal.
