Hello guys, Currently I'm setting my eyes on the M10 and M20 ballheads from Markins where I'm going to use it with my D200 with the 70-200 VR. But before I make any move, I would like to get some inputs from some of the Cafes' users here on both of the ballheads. Apart from the bigger size, able to handle more weight etc etc, what other differences are there between the two? Maybe, for example, "smoother" movement of the ballheads? If there are any more, I would love to hear it from you guys. Another thing is that I browsed through Markins website and it seem that Markins do not make/sell L-plate. If I were to get myself an L-plate for my D200 (with its battery pack) which brand or make should I buy?
