• the 24mm shift lens is the traditional architectural lens for a 35mm full frame camera
• the Canon TS-E has both tilt and shift, and the latest version has much better optics, closer focusing and improved mechanics than the original version

• 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
• Sub-wavelength structure and super-spectra 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 close-up magnification: 0.34x)
• 82mm filter

• introduced April 1991
• 11 elements in 9 groups
• 8 blades
• close focus 0.3m
• 84deg field of view; 0.3m macro; 72mm filters; 8 blades; pre2009: $A2319 RRP; ($A1750 new online) $US900
• not as sharp as the 45mm or 90mm TS-E (nor OM shift lenses)

  • many reverse the factory default lens tilt-shift orientation otherwise the tilt tends to counteract the shift but this causes some vignetting on full frame
    • The lenses come preset from the factory with the axes opposite each other, but a Canon service center can adjust them so that they are on the same axis. This way you can use Scheimflug and a rising front (for example) at the same time.

• the tilt mechanism enables one to get all the scene in focus without resorting to extremely small apertures

• shift mechanism allows perspective control

• place the camera on a tripod and use the shift mechanism to take 3 separate images which can then be stitched to create a panorama

• derived from http://www.cambridgeincolour.com/tutorials/tilt-shift-lenses2.htm
• 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)
  • J = lens focal length / sin(tilt angle)
• 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 Micro Four Thirds system
