The Jr.3 Deluxe kit weighs in at 1.5 lbs, 680grams. This is the lightest, best functioning gimbal head on the market, capable of supporting and balancing a 500F4 and Pro body comfortably. Yes, we still recommend a bigger HD3 or Pro2 gimbal for daily use, but if weight is your primary concern and you are travelling by air extensively, then lighten your load: Get a Jr.3 Deluxe, your back will thank you.The Jr.3 Deluxe, and our other gimbals fit any tripod with a standard 3/8"-16 threaded top. We DO NOT RECOMMEND tripods with a 1/4"-20 thread under any circumstances. Using a 1/4"-20 threaded tripod with a reducer bushing will VOID your warranty.You still need to buy 1 lensplate or replacement foot for each lens you are going to mount in your gimbal.NOTE ABOUT LARGE LENSES: If using a large Canon or Nikon lens, we HIGHLY RECOMMEND using a Jobu Design replacement foot, like the LF-C604 or LF-N604. A replacement foot will lower the centre of gravity of your lens and make it lighter. In most cases, large lenses with tall lens-collar feet CANNOT balance on a Jr.3 without a LENS FOOT. We recommend replacement feet for the Nikon 300F2.8, 200-400, 500F4 and 600 F4, and the Canon 500F4 (IS 1 and 2) and 600F4 (IS1 and 2) and 400 F2.8 IS.
