NIKON DK-17C -3 correction lens.
Today, the world spins so fast that people have to run to keep up with them. And some supposedly revolutionary technology only live for a short time. Nikon has never considered technical innovations as a self-purpose, but always searched for its benefit for people. Thats why Nikon microscopes, binoculars or cameras are still in use today, which have been purchased years or even decades ago. Innovative, reliable, robust, durable - thats more than a product promise. It is a part of the philosophy of Nikon. The world can spin as fast as it wants.
