Movo MT-S68 Chrome AF Macro Extension Tubes

The Movo MT-S68 set adds 12mm, 20mm and 36mm chrome extension tubes to Sony Alpha A-mount DSLR cameras. The tubes preserve full auto-focus and metering at f/5.6 or brighter, letting non-macro lenses focus closer without optical degradation. Photographers can use the tubes individually or stack them for extreme close-up magnification of insects, flowers, coins or jewellery.

Upgrading from close-up filters or single tubes

Close-up filters often soften corners and reduce contrast, while a single tube limits magnification options. This three-piece set replaces those compromises by offering three stackable lengths that maintain the lens's original optical quality. The jump is worth it when you need flexible magnification steps and reliable auto-focus for detailed macro work without buying a dedicated macro lens.

Suits Sony A-mount DSLR owners exploring macro

The set suits Sony Alpha A-mount DSLR users who want affordable macro capability with auto-focus retention for subjects like insects and textures. It is not for photographers using Sony E-mount mirrorless bodies, other brand mounts, or anyone requiring electronic aperture control on lenses lacking a mechanical aperture ring. Buyers needing weather-sealed construction should look at something else.

Questions about this item

Which Sony A-mount lenses can I attach to the 12mm, 20mm and 36mm tubes?

Any Sony Alpha A-mount DSLR lens mounts directly to the chrome AF tubes; the set maintains full auto-focus and metering on both full-frame and cropped-sensor bodies.

How do I stack the three tubes without losing auto-focus, and what aperture limit applies?

Thread the 12mm, 20mm and 36mm tubes together in any order, then mount the combined stack between camera and lens; auto-focus remains active at f/5.6 or brighter.

Do the aluminium mounts or electrical contacts need periodic cleaning or replacement?

The chrome-plated aluminium mounts and gold-plated contacts are built for durability; wipe contacts with a dry microfibre cloth if they become dirty, otherwise no scheduled maintenance is required.
