Tilt-Shift lenses have several applications for suitable photographers because of their ability to provide enhanced creative control over perspective through the tilt function and depth-of-field through the shift function in their images. This ability can be optimal when photographing landscapes, portraits, and architecture.
The image quality derived from Canon Tilt-Shift lenses has evolved considerably since their first inception several years ago. Enhanced optical elements like molded aspherical glass and UD lenses are at the core of the new Canon TS-E 50mm f/2.8L Macro lens, TS-E 90mm f/2.8L Macro lens and TS-E 135mm f/4L Macro lens. These features provide users with edge-to-edge resolution, improved image quality over previous Canon TS-E lenses and minimum distortion. Canon also included two anti-reflective coatings, SubWaveLength Structure Coating (SWC) in the TS-E 50mm f/2.8L and TS-E 135mm f/4L Macro lenses and Air-Sphere Coating (ASC), into the TS-E 50mm f/2.8L and TS-E 90mm f/2.8L Macro lenses. SWC helps to reduce flare and ghosting, while ASC is a new technology that provides amazingly high, anti-reflective performance, particularly when alleviating incidental light that can enter a lens.
The new Canon Tilt-Shift lenses also offer improved operability over previous models, including larger tilt, shift-and-lock knobs, lock-release button and a new tilt-locking mechanism that firmly locks the lens in the zero-tilt position to help prevent unintended tilting to increase more precise shooting capabilities. The rotation of the tilt-shift lenses also allows users to freely change the axis of tilt movement and shift from right angles to parallel to better adapt to various shooting conditions and situations.
The new Canon TS-E 50mm f/2.8L Macro lens, TS-E 90mm f/2.8L Macro lens and TS-E 135mm f/4L Macro lenses are scheduled to be available November 2017 for an estimated retail price of $2199.00
Review
Lens is most sharp between f/4 and f/11, but is still very sharp at f/2.8, and f/16. Sharpness drops off a little at f/22, being more noticeably soft at f/32. At the edges, you’ll find the sharpest results between f/5.6 and f/16.
