Summary: I use the MH-1001 for my canon 40d.The unit it self is very solid and has a wonderful smooth pan and ball head motion. The one issue i do have with it, is the bubble levels. They are very small and hard to see when you have the camera on the ball head.
Summary: I had this head for about one and a half months, it wasgreat and all, I loved it, and It came pretty cheap where Ihad bought it Smooth panning and all.After I got a 70-200 2.8 VR, some trouble has been comingup. I have to tighten both bolts way down and sometimestakes a while, and sometimes while doing it I have to thenreframe the shot. I also noticed the hex key bolt thattightens the quick release thingy to the ball loosens quiteoften with my 70-200.
