Ultra-wide lens Panasonic H-X012E SLR 15 elements 12 groups

This 12mm LEICA DG ultra-wide lens (35mm equivalent: 24mm) with a bright F1.4 aperture is designed for landscape, night-sky and location photography where wide perspective and fine detail are essential. The H-X012 features a 15-element/12-group optical formula, a metal barrel, hood and mount, splash/dustproof construction, and an intuitive aperture ring. It delivers high resolution to the edges, low distortion and precise rendering of points of light, making it suitable for capturing stars and small light sources as well as expansive scenes.

Advantages

The lens offers a bright F1.4 maximum aperture for better low-light performance and shallow depth-of-field control, combined with a compact, lightweight metal construction for reliable handling. Its optical design—including aspherical, Extra-Low Dispersion (ED) and Ultra Extra-Low Dispersion (UED) elements—reduces spherical and chromatic aberrations for sharp, high-contrast images across the frame. Splash/dustproof sealing and silent, smooth aperture control support outdoor use and video recording, while fast, accurate AF enables high-quality 4K video capture.

Suitable for

• Landscape photography
• Astrophotography and night-sky shots
• Architecture and interior wide-angle images
• Location and travel photography in variable weather
• 4K video recording with precise focusing

How to use

Attach the H-X012 to a compatible Micro Four Thirds camera body and confirm the mount is securely locked. Use the aperture ring for direct exposure control and set a wide aperture (F1.4–F2.8) for low-light and star shots or stop down toward F8–F16 for maximum edge-to-edge sharpness in landscape and architecture photography. For close work, set the focus to the minimum focus distance of 0.2 m; for distant scenes use AF or manual focus as needed. When recording video, enable smooth aperture transitions on your camera and use the lens’s silent operation to minimize mechanical noise in recordings.

Recommendations

For sharp landscape and architectural results, stop down to F5.6–F11 and use a tripod. For night-sky or star-point rendering, open to F1.4–F2.8 and use a stable mount with appropriate exposure settings. Keep the lens mount and seals clean to maintain splash/dustproof protection; use a lens hood to reduce stray light and protect the front element.
