The KIT-JFA fast action kit includes the Jobu Jr.3 Gimbal Head with Swing Arm HM-J2 to keep your equipment positioned exactly the way you want. It has an overall profile of 9 x 8" (22.86 x 20.32cm) and easily fits into the small pockets of your gear bags. Also included is the very sturdy MCF-284 8X Carbon Fiber 4-Section Monopod, weighing 15 oz (425.2 g), supporting up to 8 lb (3.6 kg), and folding down to only 19.5" (50.5cm), making it easy to store and transport. You also get the SF-NX1 Surefoot Lensplate which is designed to safely mount and secure most small telephoto lenses to the gimbal head.
The overall package weighs well under 4 lb (1.8 kg), making it a great choice for lightweight travel, nature and action photography.
Buying the Jobu Jr.3 Fast Action Kit is cost effective...it's almost like getting the lensplate for free.
Note: Double check to make sure your BWG-J3K is tightly secured to your monopod and tighten the pan/tilt knobs to hold everything in balance. Only carry the monopod, gimbal, and camera all assembled very short distances. Remove your camera and lens when travelling from location to location to keep your expensive equipment safe.
Maximum lens of 500mm F4 is recommended only for occasional use. The weight of a 500mm lens will require excessive tightening of the tilt axis components for travel or carrying over-the-shoulder.
