I own a Canon EOS 6D housing with EF 28-300mm zoom f / 3.5-5.6L IS USM and an EF 100mm f / 2.8L Macro IS USM and I was looking for given the weight of the unit (2Kg 700) a slight foot versatile and compact capable of responding to shoot with 300mm and 100mm macro with the different configurations. This product is very responsive to all my needs and even surprises me, especially when used in monopod. Its construction is sturdy and very well made. The leg locking system "eccentricity" is effective and timely implementation. The trolley system dovetail, based on the ball to withstand the whole, is very robust and remarkable maneuverability. Only the two "pellets" making bubble level office decorations are more than a easy use. I appreciated the support bag and quick attach system of the foot. Now the question is how it will behave over time and the conditions of shooting.
