The-Digital-Picture.com have reviewed the Canon TS-E 24mm f/3.5 L Tilt-Shift lens, which is mainly used for architecture and wide landscape photography.

“The Canon TS-E 24mm f/3.5 L Tilt-Shift Lens is not stellar in terms of sharpness. I found it to be the least sharp of the three Canon TS-E lenses. It is somewhat soft wide open, getting decent at f/5.6 with continuing improvement through f/8. Even so, I found it to be on par with the Canon EF 16-35mm f/2.8 L Lens at similar apertures. The TS-E 24mm may have a slight advantage at and beyond f/5.6. The TS-E 24mm was somewhat sharper in the corners, but still showed some extra corner softness wide open (on a full frame body). Sharpness decreases as the lens is tilted - and decreases more rapidly as the lens is shifted. Remember that sharpness isn’t everything.”
