I haven't gotten my new tripod (Gitzo GT5541LS) from B&H yet, but my friend, Jim, has that model and lent it to me. I took it for a spin yesterday to see if it would make a difference in the clarity of my shots. All I can say is, wow, what a difference!
First of all, that tripod is rock solid. It hardly moves. While it is noticeably heavier than my model I have now, the Gitzo GT3541LS, it is noticeably sturdier and beefier. When I have the lens on it, it really doesn't shake unless I give it a good tap. Combining the tripod with long lens technique and I am getting the shots, clarity-wise, that I have always wanted.
While this shot isn't a great shot, or even the best example, it does show some really nice clarity. Also, this shot has been heavily cropped so the clarity really does extend beyond full frame.
