Well With a new camera and a few lenses hopefully in my near future, I was considering Tripod heads. Now to begin with I have a few tripods that are probably overkill, But I have them so I would like to use them. Right Now I have 2 Bogen 3068 legs. Like these: http://www.bhphotovideo.com/c/product/5324-REG/Bogen_Manfrotto_3068_3068_Universal_Video_Tripod.html with 2 116 heads(same as the 3066 heads) http://www.blackswampaudio.com/Inventory/Full_Description.php?recordID=303 An One 3068 Dolly. http://www.bhphotovideo.com/c/product/5323-REG/Bogen_Manfrotto_3067_3067_Heavy_Duty_Cine_Video.html Now I got all of this stuff in a trade for next to nothing, Really I traded cash value of $8.25, so a real good deal. The Camera mounting plates were missing from the tripod heads when I got them so I have mounted a smaller quickrelease plate mechanism to one of the heads. Seen as these tripods are for full size pro video or 16mm film cameras the original plates would have been way to huge to leave mounted to an SLR anyway. The one limitation to these is pan/tilt only with no axis to move to a portrait mode, I have to mount the camera sideways and utilize the tilt. I was thingking of putting a new ball head on one, I like the grip action ones, but I need to know I these heads will work on my 3068 legs. And the combination of a 40d and 70-200 f2.8L Is getting close to the rated weight limits of the grip action ball heads I have seen, are there some heavier duty models? This I the Grip action head I was looking at: http://images.google.com/imgres?img...firefox-a&rls=org.mozilla:en-US:official&sa=N Thanks for and advice or info, If all else fails I guess I can call Bogen.
