I also added new bits and pieces to my growing collection of camera gear. This time, it was a Wimberley Tripod Head Version 2 and a P-50 attachment (for Nikon 500 F/4 or 600mm F/4).
I can't quite believe just how easy that thing makes handling cameras with large, heavy/long lenses. They are so balanced. Panning at 1/2.5sec is successful finally (at 300mm of course)!
The best $850 I've spent. It makes those Manfrotto tripod heads seem quite nasty in comparison. The freedom of movement, and the fact that the movement is so smooth and fluid makes panning type shots at very low shutter speeds much easier.
And when you set it up right, the lens and camera will be perfectly balanced and do not need to be locked to a certain angle. Wonderful!
