The TS-E 24mm f/3.5L II is one of four special tilt shift lenses on Canon’s lineup. Made for architecture and product photography, these instruments can render the focal plane out of the image plane axis, distorting the lines to compensate for some perspective distortions the photographer can’t always correct.

It’s not for everyday shots as it’s large, heavy and manual focus only. But if you work with architecture and product photography, it will definitely make a difference on your kit. Good luck!

You can buy with confidence, the lens is in a great condition, almost not used.

PS. The sample picture (last one) I took without shifting or tilting, it was taken on the day I acquired the lens, then I've never used it ever since.
