The 18mm is my bread & butter lens when doing "real estate photography", The funny thing is that I've gotten so accustomed to it that it is my standard lens for everything apart from handheld nightshots and telephoto work. My standard "telephoto lens" is the planar 50/1.4 which works like the "Imagon" between 1,4 and 2,0 and is ordinaray good lens from 2.8.
