In addition to being effective for product or portrait photography, the tilt function can also provide an effect that makes cities and landscapes appear as a miniature. This can be a great advantage in both product and portrait photography, as important objects can be precisely highlighted away from those of less importance. By tilting the lens with the tilt function you can move the depth of field line to the subject, so that objects in the foreground and background are sharp across the entire surface. With a normal lens, the aperture must first be reduced before the entire design can be captured with the same sharpness, but then the sharpness of the whole is compromised considerably. With the tilt function, the depth of field of an image can be spread over a larger area, so that objects in the foreground and background can be brought into sharper focus. This is especially useful for creating sharp panoramic images. The last option is to tilt the lens 90 degrees, which offers the possibility to use the tilt and shift function from left to right. With this function, the perspective of a photo can be corrected, making it suitable for architectural and interior photography.
The second function is the shift, with which the lens can be moved down or up to a maximum distance of 12mm. This allows the depth of field to be adjusted, suitable for landscape, miniature and product photography.
The first function is the tilt, with which the lens can be tilted down or up to a maximum angle of 8.5 degrees. There are two options for making these changes. The lens elements of a tilt-shift lens can be adjusted by the attached dials.
In the absence of an autofocus function, the tilt-shift lens has to be used to focus manually. In the beginning, the tilt and shift function were still separate, but due to the effective cooperation, they are almost always combined on a single lens nowadays. Since the 1960s, developments in both possibilities have strongly increased, resulting in a wide range of cameras with these functions. The tilt-shift lens is a lens with two possible uses for photography, namely tilt (tilt) and shift (shift).
