HELIAR-HYPER WIDE 10mm F5.6 Aspherical

Hyper wide-angle VM-mount lens with widest* angle of view in the world

Features

Hyper-wide angle lens exceptionally well corrected for distortion. Utilizes an optical design optimized for digital imaging sensors. With its 130° angle of view, this is the widest* non-fisheye lens that captures straight lines as straight lines to realize new forms of photographic expression.

Main Features

130° angle of view, extreme hyper-wide angle

Provides the widest angle of view in the world that does not distort the image like a fisheye lens. Pursues optical performance that ensures straight lines are captured as straight lines. Features lens elements with aspherical surfaces that thoroughly eliminate distortion.

Optical design optimized for digital

Employs an optical design that optimizes the angle of incident light reaching the imaging sensor to eliminate color shifts around the image periphery caused by the characteristic structure of digital camera image sensors. Features excellent contrast and resolution right into the corners even from maximum aperture.

Pan focusing

The extremely deep depth of focus means there is almost no need to focus. When the lens focusing position is set to 2m and the aperture is set to f5.6 everything from 0.5m to infinity is in focus, and when the lens focusing position is set to 1m and the aperture is set to f8 everything from 0.4m to infinity is in focus.

Minimum focus distance of 0.5 meters

The minimum image capturing distance from the subject to the imaging surface is 50cm. This lens expands the possibilities for imaging utilizing the strong perspective characteristic of extreme-wide angle lenses.

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.

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.
