I rented a Canon 45mm TS-E lens for a week and at least for the purposes of shooting miniature buildings and wanting to make them all sharp like real buildings, it was a bust. The not-close-enough minimum focus distance is what got me. I was rather impressed with the large degree of shift available, more than I expected. For the most part I thought it was just not as nice as using a proper view camera, at least not for $1500. Cripes! ƒ22 and focus stacking seems to be our lot. Although the idea of having some sort of live video output to a TV screen or a Lightroom tethered shoot seems like it would be sweet.
