Exceptional Image Quality. Among fast aperture standard lenses, the 50mm f/2 Summicron offers exceptional image quality. Its sharpness and contrast are great, even at its 2.3-foot minimum focusing distance.

Advanced Optical Design. This lens’s eight-element/five-group apochromatic design includes three anomalous partial-dispersion elements, two high-refractive index elements, and one aspherical element to improve edge-to-edge sharpness, contrast, and clarity, all while eliminating aberrations. A “floating element” retains outstanding image quality from the 2.3-foot minimum focusing distance to infinity.

Manual-Focusing Design. The 50mm f/2’s manual-focusing design gives you smooth, precise control over focus placement.

6-Bit Coding. This lens’s 6-bit coding allows the camera to apply optional “final-stage” software-based vignetting correction. The built-in, retractable lens hood provides protection from lens flare, and the front of the lens barrel is threaded to accept 39mm filters.
