The SIRUI N Series tripod has long established itself as an excellent all-purpose model with many useful features rarely found in other tripod systems. By using high quality materials and designing the leg tubes to have only a 3 mm difference in diameter. The SIRUI N-X Series tripod has a unique leg mechanism that lets you invert the legs 180Â°. This allows the tripod to be folded significantly smaller than comparably sized tripods with conventional leg designs. Simply depress the leg angle lock and flip the legs 180Â°. An added advantage is that you can keep a ball head on the tripod and it sell fits in the included tripod case. SIRUI N-X Series tripods have all the features of the famous SIRUI N-Series, with several added conveniences. The new split center column makes changing from the standard center column to the short center column fast and easy. By unscrewing the hanging hook from the bottom of the center column, the column separates and the short center column remains on the tripod, ready to go! No need to replace the full-sized center column with the short center column. In addition to being a high quality tripod, one of the SIRUI N-X Series tripod legs can be converted into a monopod! This is really convenient when tripods are not allowed or when you're shooting in tight spaces. And by attaching the larger section of the split center column onto the SIRUI N-X series monopod leg, you can significantly increase the height of the monopod.
