Where to buy

Well recognized for its remarkably compact size and excellent sharpness, this lens delivers beautifully unique images with a quality well suited for portraiture and street photography.

While this lens is often referred to as a “copy” or “clone” of the Zeiss Sonnar 50mm f/2, if you read through the history books, you’ll find that it isn’t really a “copy” or “clone” so much as it is essentially a renegade Sonnar produced by Russian appropriated German factory equipment and technology that was moved back to the Russian homeland, then re-keyed and re-died to produce the Jupiter brand. When the Soviets took East Germany at the end of World War II, they captured much of the tech that they came across in their zone, including the machinery and blueprints used to make some of the best German lenses.
