Product Description
This super-wide angle lens combines an exterior design reminiscent of the glamorous styling of classic lenses now regarded as historical masterpieces with optical performance that matches contemporary photographic equipment. By limiting its maximum aperture to a practical level, this lens combines compactness with excellent optical performance. This makes the lens eminently portable for snap shooting, which is a natural niche for a rangefinder camera.
Classical exterior
The lens has a classical design reminiscent of the famous lenses of the 1950s (early 1970s for type II). With all parts made from metal for excellent feel and operability, the lens delivers joy of ownership.
Modern lens design
In consideration for use on digital cameras, the lens utilizes an optical design that suppresses color shifts around the image periphery. Great image quality is achieved with both film and digital.
Minimum focus distance of 0.5 meters
The lens focuses beyond the minimum rangefinder-coupled focus distance of 0.7m all the way down to 0.5m. This feature is especially useful when using the lens on a camera with a live view function.
Focusing stick ideal for quick shooting (Type I)
Focusing can also be performed using the focusing stick in addition to the focusing ring. The focusing stick is effective for snap shooting as it enables the focusing distance to be set intuitively just by feeling its position.
Focusing tab for ease of operability (Type II)
The focusing tab is shaped to fit your finger to ensure fast and precise focusing.
Bayonet type hood (sold separately)
The bayonet type LH-11 lens hood manufactured from aluminum and finished with crystal paint highly valued for its classical texture is available 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.
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.
