Markins Q10 ballhead question
I have a Markins M10, which is very similar ( if not identical ) to the Q10.
I can be very short about the ballhead: it's the best ballhead ( of this size ) in the world !!!
I use my M10 on a Feisol CT3442, and won't hesitate to use this combo with my D7000 ( or D200 ) and 300 f4 + 1.7 TC. But I prefer a heavier tripod.
The only drawback from the CT-3442 is with strong wind, when the legs start to vibrate. This is no isue for my Feisol CT-3371. It could be that all lightweight tripods have this isue.
