I have Manfrotto 190xprob with Giotto MH 1001-652 ball head. From specs the maximum weight supported by head is 5 Kg ( and tripod is 8.5 Kg). I use the following setup
Canon 40 D - 750gm
Canon 100 mm f 2.8 macro - 600 gm
Canon 430 EX - 300 gm
Total weight comes out to be 1.650 Kg, to be on safe side lets take as 2 Kg... still the setup is much below the max load of the tripod + head. When i put my cam on live view, i can see the scene is not stable ( as expected), rather there is some visible shaking.
Is there any problem with my setup, or the way i use it.
