Electronic Autofocus Extension Tubes for Z Mount Lenses — 1pc 12mm + 1pc 24mm

Electronic autofocus adapter rings designed for Z mount lenses, providing a convenient automatic extension tube solution for macro photography. The set contains 1pc 12mm and 1pc 24mm; each tube works independently or can be stacked together to fine-tune the lens's minimum focusing distance. These tubes contain no other components, so they will not reduce the lens's image quality. Electronic contacts maintain full communication between camera body and lens, preserving autofocus and auto exposure functionality. Lightweight in construction, the metal stand adds durability and is built to endure frequent lens and tube changes over long-term use.
