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-bladecircular aperture diaphragm.
