Juego de anillos intermedios Novoflex Visoflex II/III LEM/VIS III para enfoque de objetivos Leica M

The Extension Tube Set Novoflex Visoflex II/III LEM/VIS III for Leica M lens focusing is an accessory designed to be used with Leica M cameras and M-mount lenses via the Visoflex mounting system. It increases the effective distance between the lens and the camera sensor, allowing closer focusing distances and higher reproduction ratios for close-up and macro photography. The set does not include optical elements, so it preserves the original image quality while changing the focusing range mechanically.

Advantages

The extension tube set provides a mechanical solution for achieving greater magnification with Leica M lenses without introducing additional glass into the optical path. It maintains lens characteristics such as contrast and sharpness because there are no corrective optics inside the tubes. The modular design supports insertion and removal to adjust the extension length, enabling flexible control of working distance and depth of field for detailed subject capture. Compatibility with the Visoflex II/III mount ensures stable attachment and reliable mechanical coupling between camera and lens.

Suitable for

• Close-up and macro photography with Leica M lenses
• Product, detail and texture photography
• Experimental photographic setups requiring increased reproduction ratio
• Situations where optical neutrality and preserved lens characteristics are required

Key specifications

• Mount compatibility: Visoflex II/III system for Leica M lenses
• Function: mechanical extension tubes without optical elements
• Purpose: increases lens-to-sensor distance to allow closer focusing
• Effect on image: no added optics, maintains original lens rendering
• Use case: adjustable extension length via modular tube sections

How to use

Attach the extension tube assembly between the Visoflex mount and the Leica M lens according to the Visoflex mounting procedure. Compose and focus using the camera’s focusing mechanism, bearing in mind that infinity focus will no longer be available at extended settings and working distance will be reduced. Change or remove individual tube sections to adjust magnification and required working distance; make fine focus adjustments and use a tripod or stable support to compensate for the shallower depth of field typical in close-up photography. Metering and exposure can be set on the camera, and manual exposure or exposure compensation may be necessary depending on light falloff and magnification.

Recommendations

Use a tripod or stable support and remote release when shooting at high magnifications to avoid camera shake. Consider using live view or focus peaking for precise focusing with Leica M lenses. Allow more light or increase ISO/shutter time to compensate for light loss at close focusing distances. Store the tube sections in a dust-free environment when not in use to protect mounting surfaces.
