The Canon TS-E 17mm f/4L Tilt-Shift Lens is, at review time, the widest tilt-shift SLR lens made . It is also one of the highest quality (both optically and physically) 17mm lenses made.

Still on discovering phase (Three month use). The full manual operation is part of the "personality" you have to deal with. Shift option makes easy panoramas. The quality of the picture is the reward of time spent for composition and setup.

The best wide angle lens ever

This is Canon's widest tilt-shift lens, and therefore a great choice for architectural photography. You can use it to keep parallel lines parallel. You can also do the opposite: exaggerate the apparent convergence, to emphasize the height of a tall building, say.

I love this lens and bought it for Real Estate photography. I debated between this and the TSE-24. If I had it to do again I would buy the TSE-24 and use my Tokina 16-28 when I needed to go wider. From what I have seen and read the TSE-24 is simply amazing.

I shoot architecture professionally and this lens mated with a 21MP full frame is a dream come true. I also use the lens for landscapes and panoramas, although, the 24 TS-E might be better suited for that application as it allows for front filter use, includes a lens hood and does not have the...

Nearly perfect even with large shift/tilt movements; The best architecture lens around, especially when mated with 21MP full frame bodies
