Pixco Mount Adapter Ring with Helical Focus for Canon EF EOS Lens to C Mount Camera Macro to Infinity Adjustable for Industrial Machine Vision
Product Description
This innovative adjustable lens adapter is designed to bridge Canon EF/EF-S mount DSLR lenses with C-mount industrial cameras, surveillance cameras, or microscope imaging systems. It ingeniously integrates a standard adapter with a helicoid macro extension tube. By rotating the adapter body, you achieve continuous manual focus, allowing your EF lenses to seamlessly transition from extreme close-up macro shots to distant infinity focus, significantly expanding their utility in specialized imaging applications.
Key Features
1.Continuous Helical Focusing: Features a built-in precision helicoid mechanism. Rotating the main body allows for smooth, manual adjustment of the focus distance. It dramatically reduces the minimum focusing distance for high-ratio macro work and extends to achieve infinity focus at its longest extension.
2.Precise Focusing Range: The physical extension range of the helicoid is approximately 25.77mm (shortest) to 29.69mm (longest). This is a manual measurement and may have a slight tolerance, but it provides a substantial increase in close-focusing capability and a complete focus throw.
3.High-Precision All-Aluminum Build: Constructed entirely from high-strength aluminum alloy with precision machining. This robust and lightweight build ensures a solid, wobble-free connection, providing a reliable foundation for high-precision imaging.
4.Broad Lens Compatibility: Compatible with the vast majority of Canon EF and EF-S mount lenses (including those with built-in motors), unlocking the extensive EF lens ecosystem for C-mount imaging systems.
5.Fully Manual Operation: This is a purely mechanical adapter that transmits no electronic data. Both aperture and focus must be controlled manually on the lens and this adapter, making it ideal for industrial inspection, scientific microscopy, and other applications requiring precise manual control.
Usage Note
1.Full Manual Control: Set the focus mode switch on the lens to "MF". Aperture is controlled by the lens's aperture ring, and focus is adjusted by extending/retracting this adapter. The imaging device should be set to Manual (M) exposure mode if available.
2.Working Distance: For macro work, the actual working distance varies depending on the lens's focal length and the extension of this adapter. Practical testing is recommended.
3.System Compatibility: Ensure your C-mount device (industrial camera, etc.) has a compatible flange distance for this external optical system. Some cinema cameras may not be compatible due to flange distance or protocol issues.
