The shifting lens can change the deformation of the building. Is a normal lens okay?

You can't. Shift-axis lens can adjust the perspective by moving the optical axis, and can correct the perspective deformation. However, because the ordinary wide-angle lens does not have the structure of adjusting the viewing angle by moving the optical axis, when shooting large buildings, due to the perspective principle of low-rise and high-rise buildings from near to far, bow effect (big bottom and small top) will inevitably appear. LZ, just look at the shift lens. If you must shoot with a normal lens, you need two adapter rings and a dark bag. Move the lens away from the bayonet of the fuselage and connect it through two adapter rings. There is a dark bag between the two rings to ensure light tightness. This is the homemade shift lens.
