Laowa Aurogon FF 10-50x NA0.5 Supermicro APO Lens for Canon EF

The Laowa Aurogon FF 10-50x NA0.5 Supermicro APO Lens offers a maximum magnification of 50x, with interchangeable tubes providing 10x, 20x, 35x, and 50x options.

Yes, it can be used with Canon EF-mount mirrorless cameras via an appropriate adapter, or with mirrorless cameras from other brands using a suitable EF-to-mount adapter.

The adjustable NA (0.5 to 0.1) controls the lens's resolving power and depth of field. A higher NA offers better resolution and brighter images but a shallower depth of field. A lower NA provides a slightly deeper depth of field.

Yes, due to the extremely high magnifications and small working distances, specialized and often powerful lighting is required to properly illuminate the subject.

No, this is a highly specialized super-micro lens designed for extreme close-up imaging. It is not suitable for general photography tasks like portraits or landscapes.

Focusing requires precise adjustment of the lens-to-subject distance and the focus ring. Given the very shallow depth of field, focus stacking techniques are often employed for macro subjects to achieve sharpness across the entire plane.

APO stands for Apochromatic, meaning the lens is designed to correct for chromatic aberrations across multiple wavelengths of light, resulting in sharper images with better color accuracy, especially critical at high magnifications.

Ensure the lens is securely mounted. Use manual focus and the focus ring carefully, as the depth of field is extremely shallow. Verify your magnification tube is correctly attached. Check that your lighting is sufficient.

Increase the power of your external lights. Use a higher Numerical Aperture (NA) setting (closer to 0.5) if the subject and focusing allow. Consider using a longer exposure if the subject is stationary, and ensure image stabilization is off if using a tripod.

Ensure the APO correction features of the lens are functioning as expected. Check that you are not pushing the lens beyond its optimal NA range. Post-processing software can also help correct residual chromatic aberration.

Ensure the tube and lens mount points are clean and free of debris. Align the markings correctly before attempting to attach the tube, and do not force it. Consult the manual for specific attachment instructions.
