  • Quick and inexpensive way to achieve macro focus with any tube combination
  • No optical insert maintains original lens optical quality while remaining lightweight
  • Enables lens to focus closer than normal for extreme macro photography
  • Includes camera mount, lens mount, 7mm, 14mm and 28mm tube sections
  • Works with Sony NEX E-Mount cameras including Alpha a7 series and NEX models

Macro extension tubes for Sony E-Mount

This set converts existing Sony E-Mount lenses into macro-capable optics without adding glass elements. It suits photographers who want close-up reproduction ratios at a fraction of the cost of a dedicated macro lens. The tubes work with a wide range of Sony Alpha and NEX bodies including the a7 series, a6000, and NEX models.

Three tube lengths with metal mounts

The kit supplies 7mm, 14mm, and 28mm sections that can be combined or used individually to vary magnification. Both the camera and lens coupling rings are included, allowing the adapters to be used alone or stacked with the tubes. No optical inserts means the original lens resolution and character are preserved while keeping the assembly lightweight.

Passive design adds no power draw or noise

Because the tubes contain no electronics, autofocus and aperture control rely entirely on the attached lens and body combination. Exposure compensation may be required as effective aperture changes with extension. The all-metal construction resists wear from repeated mounting, and the simple mechanical design eliminates any thermal or acoustic concerns.

Questions about this item

How does the Sony E-mount interface limit what the extension tubes can achieve?

The tubes preserve the lens's original optical quality and electronic communication, but disable infinity focus; the 50 mm f/1.4 reference reaches life-size magnification when all three sections are combined.

What physical parts must align for the Fotodiox set to mount securely on my camera?

The kit supplies a body-coupling ring that locks to the E-mount flange and a lens-coupling ring that accepts the rear of any Sony E-mount lens; three stackable tubes (7 mm, 14 mm, 28 mm) sit between them.

Which installation step do users most often get wrong when assembling the tubes?

Forgetting to seat both the body and lens coupling rings before adding tubes leaves the electrical contacts misaligned, so autofocus and aperture control fail until the rings are clicked home first.
