Being bored at work today I found myself looking through a Bogen/Manfrotto produ ct guide. Coming accross the video tripods, it struck me that the #3190 pro vid eo tripod coupled with, say, the Gitzo 1570 head, might be just the thing to sup port my 8x10. It certainly looks sturdy enough (max load of 44 lbs), and the ba ll leveller would be quite nice. Has anybody used this tripod, or a tripod simi lar to it, for LF photography? Also, does anybody know if the legs actually loc k at different angles, or is it like the Zone VI and need a spreader on smooth s urfaces? Many thanks in advance.
