Meike MKCA-MKCUP Macro Reverse Lens Adapter

The Meike MKCA-MKCUP Macro Reverse Lens Adapter is a multifunctional extension tube designed for Canon EF and EF-S mount cameras that bridges the gap between casual close-up photography and dedicated macro work. Unlike basic manual extension tubes, the Meike unit integrates electronic contacts that maintain communication between the camera body and lens, preserving automatic autofocus, metering, and aperture control. This means photographers can achieve macro magnification levels without sacrificing the convenience of automatic camera functions — a significant advantage when working with small, moving subjects where manual focus and exposure adjustments would slow down the process considerably.

The dual mount functionality sets this adapter apart from single-purpose extension tubes. In standard mode, it increases the minimum focus distance to achieve greater magnification with any compatible EF or EF-S lens. In reverse mount mode, the included 58mm, 67mm, 72mm, and 77mm adapter rings allow photographers to mount a lens backwards for extreme close-up magnification ratios that exceed what standard macro lenses can achieve. The flexible cable connection, measuring 45mm x 1500mm, provides freedom to position and angle the reversed lens without the rigid constraints of a fixed tube assembly. While this flexibility aids in creative positioning, photographers working at very high magnifications should account for the need for steady support, as any movement is amplified at macro distances.
