LUMIX S PRO 50mm F1.4 (S-X50)The S-X50 is a large-aperture fixed focal length lens that delivers impressive optical performance and versatile capabilities with its 50mm focal length and F1.4 high speed. It is the reference-quality model for the most discerning photographer and sets a new benchmark in image quality for a lens of its type. A double focus system combining a linear motor and stepping motor achieves sensor drive at a maximum speed of 480 fps and achieves fast, high-precision AF. A focus clutch mechanism enables instant AF/MF switching and accurate manual focusing. The LUMIX S PRO 50mm F1.4 also excels in video recording performance with a mechanism that suppresses focus breathing. Comprising 13 lenses in 11 groups, the use of 2 aspherical lenses and 3 ED (Extra-low Dispersion) lenses effectively suppresses both axial chromatic aberration and chromatic aberration of magnification, as well as correcting astigmatism. The filter diameter of the lens is 77mm, with an 11-blade circular aperture diaphragm
