Telephoto lens
A telephoto lens is the abbreviation for a long focal length photographic lens; it is a core optical component in the fields of professional photography and long-distance imaging. Its core function is, through long focal length optical design, to achieve a close-up imaging effect on distant objects, optically magnifying a distant subject while compressing the spatial perspective relationship of the frame, highlighting the subject and blurring the background. Yongxin Optics' telephoto lens products feature high resolution, high contrast, and excellent telephoto imaging capability.

Yongxin Optics' telephoto lens products feature high resolution, high contrast, and excellent telephoto imaging capability.
Applications
Sports optics, long-range surveillance, astronomical observation, aerospace remote sensing
Key Features
Long focal length (usually ≥70mm, with 200mm, 400mm, 600mm, etc. common under full frame), narrow angle of view, high magnification; Has a spatial compression effect, can pull distant targets closer, and highlights the subject; Strong background blur capability (significant shallow depth of field effect); Often equipped with low-dispersion lens elements to correct chromatic aberration, with some supporting optical image stabilization and clear long-distance imaging.
