I have an older Manfrotto tripod and I would like to get a ball head for it. I am looking for advice on what features I should look for and any recommendations that anyone may have as to what makes/models I should look at. It will need to accommodate a 5D with a 100-400 L IS attached

Any insight that anyone can provide will be greatly appreciated.

Cheers,

WesternGuy.

P.S. Wasn't sure if this was/is the correct forum for this question. If it isn't, can a Mod please move it. Thanks.
