The Laowa Aurogon FF 10-50X NA0.5 Supermicro APO lens transforms standard cameras into powerful microscopy systems with full-frame sensor coverage. This advanced optical instrument offers four magnification levels through interchangeable tubes: 10X, 20X, 35X, and 50X magnification ratios. The lens features an adjustable numerical aperture ranging from NA0.5 to NA0.1, ensuring optimal brightness control and minimal diffraction effects across all magnification settings. A constant working distance of 20 mm provides uniform illumination conditions regardless of magnification level and eliminates the need for recalibration between different magnification settings. The apochromatic (APO) optical design delivers exceptional resolution with superior chromatic aberration control, producing images with outstanding clarity and color accuracy. This lens system supports both vertical and horizontal shooting orientations and is suitable for various sample types, from static specimens to living microorganisms. Compatibility extends to multiple camera mounts, including Sony FE, Canon EF, Canon RF, Nikon F, Nikon Z, Arri PL, L-Mount, and Fujifilm G-Mount systems. The included lens tube slip rings provide stable mounting solutions that minimize vibrations and prevent accidental focus shifts during operation. With its extensive magnification range and professional optical performance, this lens serves as a complete microphotography solution for scientific research, educational applications, and specialized photographic work requiring high-resolution magnification capabilities.
