With a trembling Velbon tripod at the slightest gust of wind, I wanted something a little heavier without spending more than necessary as an amateur. With a little fear despite the guarantee of quality due to the brand, I opted for this tripod. It is stable, easy to use and fast to unfold. The ball is very flexible horizontal traveling a little less vertically. Tested with a canon 70D + 120-400 + shoe with stabilizer lens hood + + flash cobra. Between 3 and wholesale hardware 4Kg. The quick coupler is firmly screwed on the case (lens distance) and remains in place. Once on the tripod, landscape mode, portrait, up, down, sideways, ... it does not move a muscle. Very stable and solid. The material really inspires confidence. The only drawback is its weight and possibly its size. Folded it still remains impressive but I wanted a large tripod (unfolded central column to a minimum, the viewfinder is at eye level (I'm 1,80m)). For long rides, it must be taken into account. For the lighter with the same quality, it is therefore necessarily more expensive product, the 5 stars are deserved. The spirit level is a little more significant. After a few days of use, I noticed that the grub screws, which prevent the ball from unscrewing were loose. A so check that they are properly locked. Delivery one day earlier than expected, impeccable quality amazon as usual.
