Canon Extension Tube FD 50 - Like New Condition | High-Magnification Macro Specialist for Canon FD Systems

The Canon Extension Tube FD 50 is the most powerful extension accessory in the original FD lineup, designed for photographers who want to push the boundaries of macro photography. By providing 50mm of spacing between the lens and the camera body, this tube enables extreme close-up capabilities, often reaching or exceeding 1:1 life-size magnification when paired with a standard 50mm lens. This unit is preserved in "Like New" condition, offering the mechanical precision and robust build quality that defined Canon's professional FD-era accessories. It is the perfect solution for capturing microscopic details with the legendary rendering of vintage Canon glass.

Key Features

• Maximum Magnification: The 50mm length provides a dramatic shift in minimum focus distance, ideal for insects, floral details, and abstract textures.

• Automatic Diaphragm Linkage: Features the necessary mechanical couplings to maintain automatic aperture control and open-aperture metering on compatible Canon FD bodies.

• Precision Engineering: Crafted from high-grade materials to ensure perfect alignment between the lens and the sensor, maintaining edge-to-edge sharpness.

• Anti-Reflective Interior: The internal barrel is treated with a matte, light-trapping finish to eliminate flare and ghosting, ensuring maximum contrast.

• Stackable Design: Can be used alone or in combination with the FD 15 or FD 25 tubes for even greater magnification ratios.

Condition Report

• Body: Like new. The matte black finish is immaculate, with no visible marks, scratches, or signs of handling.

• Mechanics: The bayonet mounts are crisp and secure. All internal linkage levers for aperture control operate smoothly and return to position with precision.

• Mounts: Both the camera and lens-side mounts show no wear, retaining their original factory luster.

Specialist Note

"The FD 50 is a serious piece of kit for the macro enthusiast. Unlike the shorter tubes, this one really transforms your perspective, turning a standard prime lens into a macro powerhouse. Finding this specific 50mm version in 'Like New' condition is quite rare, as these were often tossed into gear bags and heavily used in the field. This example is a true collector-grade accessory."
