What Is A Tilt Shift Lens? Let Me Explain In Less Than 10 Minutes

A tilt-shift lens is a lens which can be tilted and shifted, so the lens plane is not parallel to the camera sensor, and the imaging circle is moved from the centre. This allows photos to be taken from different perspectives and with more uniform image quality across the image. Tilt-shift lenses are used in architectural photography, straightening verticals rendered crooked or converging by conventional lenses, and they are also used where creative depth of field is required.
