## Long description

Extension tubes JJC Macro Extension Tubes AF for L-mount (Panasonic/Sigma/Leica) — model SB8122 enable macro and close-up photography by increasing the distance between the lens and the camera sensor without introducing additional optical elements. These extension tubes are designed for L-mount systems and maintain electronic communication between camera and lens, preserving autofocus functionality and electronic aperture control. The set provides a practical way to achieve higher magnification and closer focusing with existing lenses, useful for product shots, nature details and other macro applications.
Advantages
The extension tubes operate without glass, so optical quality of the attached lens is not degraded. They support electronic contacts to allow aperture control and autofocus where supported by the lens and camera body. The modular tube design offers flexibility to select different extension lengths to vary magnification and working distance. Constructed to match L-mount mechanical specifications, the tubes provide secure mounting and reliable electrical connection for consistent performance.
Suitable for
 Close-up photography of small objects and details
 Product and tabletop photography for e-commerce and catalog images
 Nature and macro photography of plants, insects and textures
 Experimental and educational macro imaging without buying dedicated macro lenses
Key specifications
 Mount compatibility: L-mount (Panasonic / Sigma / Leica)
 Function: mechanical extension without optical elements
 Electronic contacts: preserved for aperture control and autofocus support
 Material: metal and durable construction matching mount tolerances
 Configuration: modular ring set allowing variable extension lengths
 Use case: increases lens-to-sensor distance to achieve higher magnification
How to use
Attach the selected extension tube or combination of tubes between the camera body and lens following the mount alignment marks. Make sure contacts are seated and the rings are fully locked to ensure electronic communication. Compose and focus as usual; note that with extension tubes the focusing range moves closer, so autofocus speed and accuracy depend on the lens and camera compatibility. Adjust aperture via camera controls if automatic aperture is supported; otherwise use manual aperture on compatible lenses. Remove the tubes to return to normal focusing range.
Usage recommendations
Use a tripod or stable support to reduce camera shake at close focusing distances, and employ live view or focus magnification for precise focusing. Be aware that available light decreases when using extension tubes; consider increasing ISO, using a faster aperture where possible, or adding continuous or flash lighting. Test different combinations of tubes to find the optimal magnification and working distance for your lens and subject.
