What does lens shift mean?
At this time, the lens angle may be insufficient, and it is necessary to change a lens with a wider angle. For a 35mm camera, the equivalent method is to shoot directly at the target with a lens with the same focal length but a larger viewing angle, and move the film to the reserved position when cutting (actually, the lens translates in the opposite direction). This kind of lens is the "axis-shifting lens", and the principle is as mentioned above.
Application of axis-shifting lens
Axis shifting lens is mainly used for architectural photography and advertising photography. 135 axis-shifting lens itself is less because of its special use, and there are also fewer DX and film in this respect. Tilt-shift photography refers to the works created through the shift lens, and the photos taken are as special as miniature models.
The function of shift lens was originally used to correct the perspective problems caused by ordinary wide-angle lens, but it was later widely used to create photographic works that changed the focus position of depth of field. Moving mirror photography is to make the real world confuse the false with the true, and let the photos fully show the feeling of "artificial city".
