The new, May 2009, Gitzo 3541xls carbon tripod with the new Wimberley nested head supporting the Nikon D300 and the Nikon 500vr. A perfect combination of stability and weightlessness for this heavy combo. Hotly recommended for solid budgets. The two previous images are taken with this set up. For the Nikon 500 you need to unscrew the Nikon mount (four screws) and replace it with the Wimberley AP553 quick release plate which slides into the nested rest. Each lens has its particular plate.
