EF to EOS M Auto Focus Adapter

This lens mount adapter enables Canon EF and EF-S lenses to be used on Canon EOS M mirrorless cameras. It measures 7.2 cm in diameter and 8.4 cm in length, and weighs approximately 180 g (typical for zinc alloy adapters of this size). The core is constructed from durable zinc alloy with gold-plated electrical contacts for reliable signal transmission between lens and camera body. The adapter supports electronic aperture control and compatibility with the camera’s built-in image stabilisation (IS) system. Autofocus functionality is retained, though focus speed may be reduced when using prime lenses compared to native EF-M lenses. A standard 1/4-inch female tripod thread is integrated into the base for secure mounting on tripods or accessories. Package includes one adapter unit and a bilingual user manual in English and Chinese.
