Extension tube set Meike DG for Canon AF2 – automatic contacts for electronic aperture and AF

The Meike DG extension tube set for Canon AF2 mounts allows photographers to achieve greater subject magnification without a dedicated macro lens. By increasing the distance between the lens and the camera sensor, the extension tubes keep electronic communication intact so aperture values and autofocus signals are transmitted where the lens and camera support those functions. The set is lightweight and reversible, making it a practical option for close-up, product, and nature photography when higher magnification is required.

Advantages

The Meike DG extension tubes maintain automatic contacts for electronic aperture control and autofocus, ensuring compatibility with Canon AF2 lenses and bodies that support electronic communication. The tubes provide a compact and economical way to convert ordinary lenses into close-focusing optics while preserving EXIF aperture information and exposure metering. Their reversible installation allows quick removal when standard focal distances are needed, and the aluminum and plastic construction balances durability with low added weight.

Suitable for

• Close-up and macro photography of small subjects
• Product and detail shots in studio or on location
• Nature and insect photography requiring higher magnification
• Photography practice to explore magnification techniques without investing in a macro lens

Key specifications

• Mount type: Canon AF2-compatible mount
• Preserves electronic aperture control and autofocus signals when supported by lens and camera
• Set composition: multiple extension tubes (stackable) to vary magnification
• Material: metal and high-strength plastic components for a balance of durability and light weight
• Reversible design for quick removal and normal lens operation

How to use

Attach the appropriate tube or combination of tubes between the camera body and the lens to achieve the desired magnification. Mount the lens to the front of the extension tube and ensure that the tube locks securely to both the lens and camera. Use live view or viewfinder focusing to locate and fine-tune the focus point—manual focus or autofocus can be used depending on lens and camera support. Metering and aperture control remain available through the camera; adjust exposure and aperture as needed to achieve the required depth of field and sharpness. When finished, remove the tubes and reattach the lens directly to the camera for normal shooting.

Usage recommendations

Use a tripod or support and enable mirror lockup or electronic shutter functions where available to reduce camera shake at close distances. Consider focus stacking and smaller apertures to increase depth of field, and be aware that effective autofocus performance may decrease with increased extension and certain lens types.
