Gitzo的1系說明書話支腳架承重到8Kg,但建議最盡只可承重單反+200mm鏡頭。Manfrotto最大的炭架55系列的最大承重係8Kg，按Gitzo講法，是否最盡只可承重單反+200mm鏡頭?

唔會啩，單反 + 200mm ，邊有 8kg 重？

Gitzo話除了要考慮腳架的承重外，重要考慮鏡頭的視角，越窄視角，好似400mm，支架就要越穩定。以下係說明書的部份:
"maximum load capacity is no longer enough to let you identify the correct support for your setup. If you only consider maximum load, you may find yourself using a tripod that’s strong enough to hold your equipment, but
not sturdy enough to properly stabilise your images, no matter how
good your camera or lens." "A 200mm lens has a view angle of 12°, while a 400mm lens has a 6° view angle. A deviation of 6 degrees projected over a distance of 300m is equal to 31.5m. To take these constants into account, the ideal tripod should really be selected according to its torsional rigidity. The tripod’s torsion angle should always be inferior to the view angle of the longest focal length lens you intend to use." "For example, we recommend Series 2 tripods for use with 200mm lenses. If you decide to use a 200mm lens on
a Series 1 tripod, you’ll need to pay more attention to keeping
your equipment steady and may have to avoid critical conditions
like strong winds."

名廠腳架原來包埋理論，貴都值得。

如上文所述，我相信對其他腳架一樣適用。

但文內最後說明表示 Series 1 也可以用單反配 200mm ，只不過 you’ll need to pay more attention to keeping your equipment steady and may have to avoid critical conditions like strong winds 吧了。

多謝分享。

fix your camera bag at the bottom of the tripod so as to steady your tripod
