The 190XPRO4 is a super-compact 4-section aluminium tripod with advanced features and excellent build quality.The key feature of the 190XPRO4 is its 90 Degree center column mechanism, which allows the column to be extended vertically as normal, or horizontally. The horizontal column mechanism is housed within the tripod's top casting for compactness, but it is easily and quickly extended whenever you need it. Switching between vertical and horizontal column orientation requires no disassembly, and can even be done with a camera attached.The 4-section legs of the 190XPRO4 tripod make it extremely compact: together with the height saving of the new horizontal column mechanism, 4-section legs help to reduce the closed length of this tripod by 16cm compared to preceding 190 models - a boon for any travelling photographer. The legs are also fast to extend and adjust, thanks to the Quick Power Lock levers that block and unblock each leg section. The special design of the QPL levers allows a single-handed grip of the leg locks. A bubble level is built in to the top of the center column for precise framing. The bubble level rotates freely around the Centre column, so it can be positioned wherever it's easiest for you to see it. The X-PRO 3-Way Head has retractable levers which make it ultra-compact, and also features new friction controls on the portrait and tilt axes, to help balance the weight of camera equipment so that fine framing adjustments can be made with the locking knobs open, only locking everything down once the shot is ready.
