Extension Tubes Viltrox DG-NEX for Sony A7/A7R/A7S/A7 II — 2-piece set

Viltrox DG-NEX extension tubes for Sony A7/A7R/A7S/A7 II are a two-piece set (10 mm + 16 mm) that mount between a compatible lens and the camera body to shorten the minimum focusing distance and increase subject magnification. These extension tubes contain no optical elements and maintain the original lens optics while allowing closer focusing for macro and close-up photography. Electronic contacts provide communication between lens and body, preserving autofocus and exposure control where supported by the lens and camera.

Advantages

The set converts standard lenses into close-focusing tools without affecting image quality because there are no additional glass elements. Supplied as two separate tubes (10 mm and 16 mm), each tube can be used alone or combined for greater extension and higher magnification. Built-in electronic contacts transmit aperture, focus and exposure information to the camera, enabling automatic exposure and autofocus functionality with compatible lenses. The lightweight construction keeps handling balanced while increasing versatility for product, nature and detail photography.

Suitable for

• Macro and close-up photography of small subjects
• Product and detail photography for e-commerce or catalog work
• Nature photography of insects, flowers and textures
• Creative shooting where shorter minimum focus distance is needed

Key specifications

• Compatibility: Sony E-mount full-frame and APS-C mirrorless bodies in the A7/A7R/A7S/A7 II series
• Set composition: two extension tubes of 10 mm and 16 mm; usable individually or combined
• Optical design: no optical elements (mechanical extension only)
• Electronic contacts: yes — supports aperture control, autofocus and exposure transmission when supported by lens/body
• Effect: decreases minimum focusing distance and increases subject magnification
• Material and build: lightweight construction designed for secure mounting between camera and lens

How to use

Mount the chosen extension tube directly onto the camera body, then attach the lens to the tube. Use the 10 mm or 16 mm tube alone for moderate magnification or attach both for greater extension. Compose and focus as usual; with shorter working distances and shallower depth of field you may need to use manual focus or focus stacking for critical sharpness depending on the lens and subject. Check camera settings for exposure compensation and stabilization; some lenses may require a profile adjustment for close-focusing performance.

Usage recommendations

Use a tripod or stable support to reduce camera shake at close distances, and consider manual focus or focus peaking for finer control. When higher magnification is required, combine both tubes and use smaller apertures or focus stacking to increase depth of field. Verify compatibility and autofocus behaviour with your specific lens model before critical shoots.
