Haha, okay, I will just say nothing about this quirk Maybe pick up an extra battery or two. Careful when you buy them, I believe that it uses a different battery than the D200 (which has a CCD, btw, and is meant to have great colour, if nonsensical high ISO performance; I have wanted to try one and compare).
I use the newer G zooms, the 24-70 is perfect, and don't know much about the older ones, but if you want to keep up the theme, the 35-70/2.8 is meant to be good (no typo).
For the studio, it could be a perfect set of focal lengths from normal to tele effective. As a neutral lens, the 60 Micro is very good, very neutral rendering, but maybe you have that covered with the 55 Micro, I don't know it. The 105 you have is obviously fantastic, one of the best lenses ever made with beautiful rendering.
Maybe try a manual focus length first, and see how you get on, perhaps the 55 or 105? The 50/2 might also be worth a try. Alex in Russia recently calibrated his focusing screen on his S5 carefully, and found that he got a high keeper rate.
I am very curious to hear how you get on with this camera, whether positive or negative. Do spend some time processing images from it and see how you like the files. Maybe read the manual first, to avoid getting stumped by the oddities in the menus.
