Well after my mental debate i ordered the D300 from B&H just now since it was in stock. I also ordered the 180mm 2.8 new. I think a 270 mm will serve me very well for the runway stuff. I still have some stuff to sell to expand the Nikon line but I know the 85 pc lens is something i need and maybe the 24 shift than a zoom at some point mid-range. This camera will have to target specific needs outside my M8 realm.
