Camera accessory for Micro Four Thirds systems, designed to let lenses focus much closer and unlock macro possibilities. Enthusiasts gain a straightforward way to capture fine detail and tabletop subjects with existing lenses. Are the benefits of JJC M4/3 Extension Tubes enough to expand a kit for close-up work?
⚡ At a Glance
- • Image Quality: Preserves original lens optics while enabling significantly closer focus
- • Best for: Photographers experimenting with macro and close-up work on Micro Four Thirds bodies
- • Not ideal for: Users who need dedicated 1:1 macro performance from specialised macro lenses
10mm and 16mm extension tubes fit Micro Four Thirds mounts and maintain electronic coupling for autofocus and TTL metering. Metal bayonets and gilt contacts ensure secure mechanical and electrical connections.
Closer Focusing for Macro Shots – Thanks to 10mm and 16mm extension tubes
Adding physical spacing between lens and sensor shortens the minimum focusing distance, increasing magnification. Tubes can be used individually or stacked together to vary close-up reach.
Standard lenses turn into useful close-up tools for flowers, small products and tabletop scenes, without changing optical elements.
Autofocus and Accurate Exposure – With electronic AF and TTL coupling
Gilt metal contacts and internal circuitry pass focus and exposure signals between lens and camera, preserving autofocus and automatic TTL metering across compatible bodies. Full electronic coupling keeps metering and AF functions operational.
AF-assisted focusing and automatic exposure remain available for handheld shooting and quick workflow when moving between subjects.
Secure Mounting and Durable Build – With metal bayonets and mixed-material construction
High-quality brass, aluminium and ABS plastic components form the mounting structure, with metal bayonets for precise fit and gilt contacts for reliable electrical connection. Design minimises play between lens and body.
Firm, repeatable lens attachment reduces wobble during careful focusing and gives confidence when changing tube configurations in the field.
