By MH054Mo-Q2 changed all of this for the better. The ball head has a very balanced and yet catchy design and is made of a lighter magnesium alloy, so it will fit on my EOS 7D. The quick-change unit called recently Q2, but is fully compatible with the old familiar 200PL plates of Manfrotto, it is precisely such Schnellwechelplatte attached to the head. The backup is performed using a strap held by a spring, are on the top notches holding the locking bracket in the open position or retained in the closed position against unintentional opening. Mir has indeed with the retractable locking pin also like the old system well, but am always open to new and there have been no problems.
The friction setting seemed a little tight fit on the first try and the ball did not seem to be much smoother, but when then the 2kg heavy camera was mounted, I found the right resistance. When clamping the ball then moves nothing, everything very firmly. The Panorama dial can be performed elegantly and 30 ° markings legible, the lines for further subdivision but worse.
According Manfrotto which ball is placed in a dish of so-called Sliding plastic, I think here is it is PTFE (Teflon), as this unlike many other plastics have very good sliding properties. This technique eliminates the need to grease the ball and thus contributes in good measure to ease in.
