technical field [0001] The invention relates to a camera, in particular to a single-track axis-shifting large-frame camera. Background technique [0002] Cameras are divided into large cameras (4×5 inches, 5×7, 8×10, 10×12, 20×24), medium-sized cameras (using 120 film) and small cameras ( 135 film, APS film) three categories. Large-format cameras, also known as large-format cameras, are mainly used in professional photography, such as studio still life, commercial advertising photography, outdoor architecture, landscape photography, etc., and are used by professional photographers and photography enthusiasts. [0003] Large-format cameras are divided into dual-track cameras and single-track cameras according to the basic track structure. Due to the limitations of its own structural design, the dual-track camera's shifting performance is greatly limited. Although a long focal length that can be extended by 2-3 times is very practical, it also greatly reduces the stability ...
