Leica APO-SUMMICRON-M 50mm f/2 ASPH. Metal Grey: Optical Perfection Without Compromise

A Reference-Class Apochromatic Lens

The Leica APO-SUMMICRON-M 50mm f/2 ASPH. represents one of Leica's most advanced optical achievements. Its apochromatic design brings red, green and blue wavelengths into the same focal plane, virtually eliminating chromatic aberrations.

The sophisticated optical formula incorporates three anomalous partial dispersion glass elements and two high-refractive-index elements, delivering exceptional color accuracy, impressive contrast and outstanding clarity at every aperture.

Exceptional Sharpness Thanks to the Aspherical Element

A precision-engineered aspherical element effectively minimizes spherical aberrations.

Benefits include:

• Outstanding edge-to-edge sharpness.
• Excellent image uniformity.
• Precise rendering of textures and fine details.
• Consistent performance even at maximum aperture.

Floating Elements System for Consistent Performance

A floating element system maintains optimal image quality throughout the entire focusing range.

Advantages include:

• Consistent sharpness from close focus to infinity.
• Improved correction of optical aberrations.
• Uniform image quality in every shooting situation.

Optimized Optical Formula

The optical design combines a Gaussian-type construction in front of the aperture with a configuration inspired by the renowned Summilux-M 50mm f/1.4 behind the aperture.

This sophisticated architecture provides:

• Significantly reduced distortion.
• Uniform illumination across the frame.
• Exceptional sharpness.
• The natural three-dimensional rendering Leica lenses are famous for.

Bright and Versatile f/2 Aperture

The fast f/2 aperture offers an ideal balance between brightness, compactness and performance.

Benefits include:

• Excellent low-light capability.
• Beautiful background separation.
• Precise depth-of-field control.
• Natural-looking portraits with smooth bokeh.

Compact Design for Everyday Photography

With its compact dimensions and manageable weight, the APO-SUMMICRON-M 50mm f/2 ASPH. is designed for everyday use.

The versatile 50mm focal length is ideal for:

• Street photography.
• Reportage.
• Portrait photography.
• Travel.
• Documentary work.

Precise Manual Focusing

Like all Leica M lenses, this lens features exceptionally smooth and accurate manual focusing.

Focusing Features

• Minimum focusing distance: 0.7 m / 2.3 ft.
• Maximum magnification: 1:11.3.
• Leica focusing tab for enhanced control.
• Perfect compatibility with Leica M rangefinder cameras.

Integrated Lens Hood and Enhanced Protection

The integrated extendable lens hood offers:

• Effective flare reduction.
• Reduced ghosting.
• Additional front element protection.
• Convenient deployment without separate accessories.

The lens also accepts standard 39 mm screw-in filters.
