Incredible compactness : 28mm length, 189g, 43mm filter size !

Symmetrical optical configuration

This lens achieves its compact size and large F1.4 maximum aperture through the combination of a traditional symmetrical optical configuration and the latest optical materials (ultra-high refractive index glass).

Imaging controlled by aperture setting

This lens reproduces the characteristic imaging of a classic lens. At maximum aperture, the gentle and smooth bokeh gives images a sense of three-dimensionality. And when the aperture is stopped down, images are very sharp, making diverse photographic expressions possible with this one lens.

Two types of lens coating to choose from

The multi coated (MC) version aims to reproduce colors that are as neutral as possible and the single coated version aims to reproduce classical color tones. This lineup offers a lens coating to match your taste.

Dedicated bayonet type lens hood

A durable and beautiful metal dedicated bayonet type lens hood that only slightly protrudes into the field of view when the lens is attached to a rangefinder camera is provided as an optional accessory.

Manual focus for reliable focusing

Employs a very precisely machined and adjusted all metal helicoid unit lubricated with high quality grease to realize smooth focusing operation with just the right amount of torque. This enables very precise focusing.

Focusing tab for ease of operability

The focusing tab is shaped to fit your finger to ensure fast and precise focusing.

Bayonet type VM mount

Uses the VM-mount lens mount compatible with Leica M-mount. Not only can this lens be used on rangefinder-coupled cameras, but design-wise it also balances very nicely when mounted on mirrorless digital cameras with a mount adapter.

Installed with a focus-coupling system

The high-precision rangefinder coupling mechanism enables precise focusing in focus critical situations such as when shooting at or close to maximum aperture.

Imaging circle that covers full frame format

The lens features a generous imaging circle that covers the 35 mm full frame format. Furthermore, its size is extremely compact compared to interchangeable lenses for single-lens reflex cameras.

Improved focusing accuracy with live view

In order to address the issue of focus shift where spherical aberrations caused the point of focus to shift backward when the lens was stopped down to capture an image after being focused at maximum aperture, the amount of image plane shift caused by changes in the aperture setting has been reduced.
