Hi Terence,
I use RRS plates on all my cameras mounted onto either the RRS BH-55 ballhead or the lightweight Acratech (original) ballhead. This combo has worked flawlessly for years. One caveat though...if the mounting plate on your ballhead uses a "quick clamp" style setup, then be VERY careful which plates you use. For example, RRS warns its customers that the Acratech plates are not safe to use with their ballheads. I think it has something to do with a very slight difference in height. Anyway, you should check this out if it applies to your situation. Ballheads with screw-type clamps are not an issue; apparently, they're okay with any plate.
Hope this helps. |
