Tilt-shift lenses are really special. It sounds like they have some disability. No not really but this kind of lenses are primary intended to take pictures of architecture, because parts of the lens group can be pan this prohibit that buildings in picture leveling will be distorted bottom-up. Authentic architecture photographers confirm on tilt- and shift lenses oath. Most of them wouldn’t like to take photos without it. These lenses are like all special lenses expensive, a good tilt-shift lens starts at $1,900 (1.700 €).
I don’t use tilt-shift-lenses because I don’t need that kind of itemization of architecture.
