For those of you who might be interested, DPreview has a review of the above-mentioned lens. I sure wish I had the $ to buy it although I'd probably not use it that often. However, FWIW, I've found T/S lenses to be of great help under certain conditions in the field (not just architectural use). I'm off to Oregon in mid-August to visit my brother and do our annual backpack to Jeff Park (a very scenic section of the Jefferson Wilderness in the Cascades) and, from past experience, were I to be lucky and have the wildflowers in bloom this time, I sure could use a lens like the aforementioned to keep the fore, mid, and backgrounds in focus at a reasonably fast f stop (constant breezes) so as to get the flowers, Russell Lake, and Mount Jefferson in the frame without motion blur.
