With big glass, a ball head is a bad choice. If you must have the option of using other lenses, go with a heavy-duty three-way head, like the Bogen/Manfrotto 3047. But I would opt for the gimbal here. What does the Manfrotto 393 sell for? I'd like to have one myself for my A400/5.6. On Jan 8, 2008, at 7:19 AM, Patrick Genovese wrote:
