Lens mount adapter KiwiFotos for Leica M to Sony E — Close Focus II (VG3273)

The KiwiFotos Lens mount adapter Close Focus II (VG3273) allows Leica M lenses to be mounted on Sony E-mount mirrorless cameras while retaining mechanical coupling for rangefinder lenses. The adapter provides a close-focus feature that reduces the minimum focusing distance compared to a simple passive adapter, and it preserves manual control over aperture and focus. It is designed for photographers who prefer the optical character of M-mount glass and need reliable mechanical alignment when using those lenses on Sony full-frame and APS-C bodies.

Advantages

The adapter maintains a solid mechanical connection between Leica M lenses and Sony E-mount cameras without electronic communication, ensuring compatibility with manual rangefinder lenses. Its close-focus mechanism increases versatility by enabling shorter focusing distances for portrait and detail work. Constructed to fit precisely, the adapter preserves lens optical axis alignment and supports full manual aperture control and focusing feel native to the lens. The metal construction provides durability and stable mounting for heavier vintage lenses.

Suitable for

• Portrait photography using Leica M prime lenses on Sony E-mount bodies
• Street and documentary work where manual focus and compact lens setups are preferred
• Close-up and detail shots that benefit from reduced minimum focus distance
• Use of vintage and modern M-mount optics on Sony mirrorless cameras

Key specifications

• Mount conversion: Leica M (female) to Sony E (male)
• Close-focus functionality for reduced minimum focusing distance
• Manual aperture control retained on lens
• Manual focus operation with mechanical coupling for rangefinder lenses
• Metal construction for durability and stable lens mounting
• Compatible with full-frame and APS-C Sony E-mount cameras

How to use

Attach the adapter to the Leica M lens by aligning the mount indexes and rotating until it locks into place. Mount the lens-plus-adapter assembly onto the Sony E-mount camera bayonet and secure it with the camera’s locking mechanism. Use the lens aperture ring to set the desired aperture and focus manually using the lens focus ring. When utilizing the close-focus feature, follow lens-specific focusing distances and stop down as needed for greater depth of field. Be aware that focus confirmation or exposure assistance depends on the camera body and settings since the adapter has no electronic contacts.

Usage recommendations

The adapter is intended for photographers comfortable with manual focus and aperture control. For best results, balance the lens on the camera body or use a support when using heavy vintage lenses. Check focus at larger apertures with focus peaking or magnification on the Sony camera when available. Avoid forcing mounts when attaching or removing lenses and keep the mount faces clean to maintain secure mechanical fit and optical alignment.
