The K&F Concept Tripod is a winner. The clever telescoping center column with ball-pivot works very well. I purchased this model because of the pivoting center column. I needed to get my iPhone7 (mounted on a RetiCam Tripod holder) close to an object for taking a macro shot. This was impossible without an extension arm, because I could not position the iPhone close enough when mounted on the regular vertical center column of another tripod due to the spread of the tripod legs. This setup works really well - holding the iPhone in the right position and steady while I take the shot.I also really like the quality Arca-Swiss style mounting plate supplied with the K&F tripod. The half of the adapter that mounts to your camera has an easy to use thumb screw so you can securely mount it (and remove it) without using a tool.I've also been using the removeable monopod feature of the K&M with my a6300 and 70-300mm Sony zoom lens. It also works very well and is easy to remove and replace on the tripod.The fit and finish of this tripod is very good. I really have nothing critical to say about it. For the price, its a great buy.
