Surface treatment technology

All camera lenses as have evolved to capture the moment better. We take this mechanism for granted, but it achieves its results at the expense of true optical fidelity. Unless, that is, you use the only camera lenses in the world designed for high image quality that makes no compromises at all: the mechanical parts zoom system. With your design and our mechanical technology, none of the optical data is lost. And by the high technology surface treatment, let the consumer have the better feeling from the outlook of the best surface treatment.
