Pomya Auto Focusing Macro Extension Lens Tube - 12mm+20mm+36mm

Our review of the Pomya Auto Focusing Macro Extension Lens Tube finds it best suited for hobbyist photographers and anyone wanting an affordable route into close-up work. The single biggest reason to buy is its combination of metal construction and conductive copper contacts, which preserve autofocus and image communication while delivering reliable close-focusing capability without the bulk or cost of a dedicated macro lens. It feels sturdy on a camera and offers flexible magnification by combining the three rings.

Key Features

• Solid metal build: The metal materials make the extension tubes lightweight yet sturdy, so they mount securely and resist wear during repeated use.
• Auto focusing support: Copper conductive contacts inside the tubes maintain electronic communication with the camera, preserving autofocus and lens data where supported.
• Three-ring set: The 12mm, 20mm and 36mm tubes can be used independently or stacked in combinations to achieve different magnification and working distances.
• No image degradation: The design decreases lens-to-subject distance for close-ups without altering image quality, as there are no optics added in the extension tubes.
• Portable macro option: The compact rings are a practical, lightweight alternative to an expensive macro lens for those exploring macro photography on a budget.

Who It's For

This kit is ideal for photography enthusiasts who already own one or more DSLR lenses and want to try macro shooting without investing in a dedicated macro optic. Its metal construction and preserved electronic contacts appeal to users who need reliable mechanical fit and retained camera communication.

Photographers who require weather sealing, the fastest possible autofocus performance in low light, or integrated optical stabilization from a true macro lens should look elsewhere; extension tubes change working distance and may slow focusing depending on the lens and camera body used.

Pros & Cons

Pros

• Metal construction gives a secure, durable mount that feels professional.
• Copper contacts maintain autofocus and EXIF communication with compatible cameras.
• Three tube sizes (12mm, 20mm, 36mm) provide flexible magnification options when combined.
• Does not add glass elements, so image quality remains unchanged when used correctly.

Cons

• Using long stacks of tubes will reduce available light and can slow autofocus, so results vary by lens and body.
• Not a substitute for specialized macro lenses when extreme working distance control or highest optical performance is required.

Frequently Asked Questions

Will these tubes maintain autofocus?
Yes. The tubes include copper conductive contacts that preserve electronic communication with the camera and lens, so autofocus remains functional on supported bodies.

Can I stack all three tubes at once?
Yes. The 12mm, 20mm and 36mm rings can be used independently or stacked to increase magnification, but stacking reduces available light and may affect focusing speed.

Do the tubes contain any optical elements?
No. These are mechanical extension tubes only; they do not include glass elements and therefore do not introduce optical glass into the image path.
