Canon has recently announced two stunning tilt/shift lenses for EOS bodies, the TS-E 24 mm f/3.5 L II and the TS-E 17mm F4 L.
Both these lenses allow the photographer to fully independently set the orientation of the tilt and shift axes, giving enlarged flexibility in exploiting these two geometric functionalities.
When tilt capability is in the news, we often hear about "the Scheimpflug principle", which helps us to understand how tilt capability should be managed. Of course, there are actually several Scheimpflug principles in this area, and two of them are directly pertinent. The clue to this is that, when setting up a photographic shot using tilt capability, there are two lens adjustments we can make, the angle of tilt and the focus adjustment. They interact in a less-than-obvious way in "tilt" situations, which is addressed by these two separate principles.
Those who have their interest in all this renewed by the emergence of these new Canon lenses might want to review my technical article, "The Scheimpflug Principles", available here:
