Hi all, I recently got a tripod (Manfrotto 728B), which says is rated up to 3.5kg. I would like to use an SLR camera on it, with a not-so-heavy lens (combined weight of camera+lens is under 2kg). It all looks good, the camera appears to be well-supported, the tripod head appears strong enough to lock it in place any way I put it. After I bought the tripod, I noticed that it says it is for point-and-shoot cameras only. No SLRs. I can't think of a 3.5kg point-and-shoot camera (unless it is lead-lined) and the one type of camera that approaches these specs is not on the supported list. I am scratching my head now. Am I missing something? Is this tripod safe to use with an SLR camera, provided that I stay within the weight limit? Thanks!
