Canon TSE 24mm f/3.5L tilt shift lens
introduction
the 24mm shift lens is the traditional architectural lens for a 35mm full frame camera
the Canon TSE has both tilt and shift, and the latest version has much better optics, closer focusing and improved mechanics than the original version
latest version (mark II)
introduced in 2009;
+/ 8.5° Tilt and ±12mm Shift
Tilt and shift mechanism rotates +/90° allowing shift in any direction
Tilt mechanism rotates +/90° allowing tilt in any direction relative to the shift
Subwavelength structure and superspectra coatings minimise ghosting and flare
Circular aperture for creative, blurred highlights
Aspherical and UD lens elements minimise chromatic aberration
74deg angle of view (84deg diag w/o t/s); close focus 0.21m; (maximum closeup magnification: 0.34x)
82mm filter
original version (mark I)
versatility of this lens
landscape photography
architecture
panorama stitching
tilt calculations

J point is the distance below the camera that will be in focus (although this point will not be in the field of view of the lens)
for landscapes, where nearly everything is in focus one usually selects a tilt and focus distance that changes the focus plane to horizontal (ie. 90deg) with the camera still aimed horizontally but placed at the J point above the ground.
thus determine how far you want to be from the ground (based on tripod, perspective, etc), then determine from the tables what tilt you will need and the focus distance to achieve close to 90deg focus plane.
camera sensor size and aperture have NO effect on the angle of the focus plane BUT do alter the total angular depth of field, and thus the calculations should apply whether you use it on a full frame dSLR or a 2x crop
