I recently received my first Gitzo tripod, a carbon fibre GT1530 which replaces my old Manfrotto 190Pro. This was ordered from BH and, as I live in Australia, I didn't actually have the chance to examine the tripod before ordering. However, given Gitzo's sterling reputation I figured this was pretty safe although now I actually have the tripod, I'm not quite so convinced.
Firstly the positives: the tripod is approximately 800 g lighter than the old Manfrotto while also being significantly taller. This makes quite a big difference as one of the intended applications is overnight or multi-day hiking. It does fold away to be slightly longer but not enough that I expect will ever matter. While about three times the price of what I paid for the Manfrotto, given the improved specification (especially being carbon fibre) and Gitzo's reputation for quality, I consider it to be good value.
However, in terms of stability I'm not quite convinced that the Gitzo is as good as the Manfrotto. My biggest complaint is that the upper disk where the tripod head attaches is both smaller in diameter and smoother than on the Manfrotto. As a result, my Acratech head does not attach anywhere near as securely. In fact, with the camera in a portrait orientation and the tripod on an angle, the head is disturbingly prone to unscrewing itself. This seems at odds with Gitzo's claims regarding their "Safe Lock" material used on head mounts. Also, the small diameter of the upper disk (obviously intended for use with Gitzo heads) means that the Acratech head sits with slightly less stability than on the Manfrotto and is more prone to slight side to side movements etc. Finally, the Gitzo legs seem to have noticeably more flex in them compare it with the aluminium legs on the Manfrotto. Is this simply a case of aluminium versus carbon fibre or more to do with the lightweight nature of the tripod?
Anyway the purpose of this message is not really to have a whinge but rather to get some feedback and see if anyone else has had similar experiences or has suggestions on how stability might be improved. In particular, I feel like there must be some way of improving the security of the mount between the head and tripod, either by increasing the amount of friction or somehow treating the bottom of the head to bond better with the "Safe Lock" material on the Gitzo. Again, any thoughts are appreciated!
