I have a Jobu Junior 3 gimbal head which I have used with both 100-400mm and 70-200mm lens. I just received my 200-400mm f4 lens and, if I believe the Jobu website, http://www.jobu-design.com/Jobu-Jr-3-Deluxe-Kit_p_16.html, I can’t consistently use the Jr3 with that lens.
I used the 500 f4 for comparison purposes as it is about the same weight as the 200-400 but has been out much longer.
It is stated on the Jobu website for the Junior 3:
“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 recommended working load for the Junior 3 is stated as “3-10lbs (ie 70-200 F2.8, 150-500 zoom, 400 F5.6)” and it is also stated “Maximum gimbals weight limits are for occasional use. Our gimbals are extremely strong, but continually overloading the gimbal will generally cause poor braking performance, extra vibration or unnecessary wear on internal components and will void our manufacturers warranty. The best performance and 'sweet-spot' for continual daily use is our recommended weight column.”
So my question for all you gimbal owners that have 500mm lens is whether any of you use a Jobu Junior 3 with your lens, have you had any issues and have you had to upgrade?? I appreciate all the help!
