Guys, I have read most of this topic but I'm still not sure, most of the sellers online use what looks like original listing, where it says 1200grams for Crane. But original site says: http://www.zhiyun-tech.com/index.php?m=content&c=index&a=show&catid=132&id=190 350-1800grams. OPTIMAL: 1600 grams??? I quote:"compatible with the payload of 350-1800g (cameras with lens), but we recommend 1600g would be the best performance." So I wonder how and why would anyone write 1200. I have 550D (530 grams with battery and card), I have 18-35mm Sigma 1.8 art, 634 grams, that is 1164grams, which would be on the edge. I plan to go for Sony 7S II, with metabones adapter and again sigma, it would be again around 1.2kg or bit more, as Sony is 627grams, + sigma, it is already 1260 + metabones adapter, at least another 100-200 grams, would be 1.4kg. Please advise. I'm about to buy it, but I'm afraid, I have as well 5D Mark II. But as I would use it for wide angle shots, not sure which lens on FF.
