Tilt-shift lenses are highly specialized pieces of equipment that many photographers will go their entire careers without ever touching. As such, you might wonder why those weird lenses are so expensive in the first place. This interesting video explores just that question.
Coming to you from ZY Productions, this great video takes a look at tilt-shift lenses and what it is that makes them so expensive. Tilt-shift lenses allow you to control both the angle of the lens plane relative to the image plane (allowing you to control depth of field independently of aperture) and to shift the position of the image without moving the camera itself (this can help correct converging parallels). This makes them tremendously useful for certain genres, particularly architecture. But those specialized capabilities come with some unique engineering challenges and thus, some higher prices.
If you've never shot with a tilt-shift lens before, I recommend renting one or picking up a used copy, even if you don't need them for your work. They're simply a bunch of fun to shoot with and will challenge your inner photography geek with their unique functions. Check out the video above for the full rundown!
