Canon TS-E 24mm f3.5L II vs Canon TS-E 17mm f4L Tilt Shift: Which Should You Buy
For architectural photography, I highly recommend you buy and use a tilt-shift lens. Personally, I prefer Canon because I firmly believe they make the best. Tilt-shift lenses are brilliant because they allow you to correct perspective; which is extremely important for the kind of work we do.
