Press Text:
Koblenz, Germany. New German lens maker Oprema Jena launched a campaign today on the crowdfunding site Indiegogo to resurrect the Biotar 58mm f2, promising to faithfully recreate the original lens’ optics down to its unique 17 aperture blade design.

The Biotar 58mm is Oprema Jena’s second lens project, following its successful Kickstarter campaign to revive the Biotar 75mm f1.5. Oprema’s plan calls for bringing some of the greatest lenses in history that are no longer being produced back to the market.

The new Biotar 58/f2 will be a truly remarkable lens that combines sharpness and bokeh in one sleek package. But what really sets the Biotar 58mm apart is what you’ll find on the inside — 17 aperture blades that will help it produce a one-of-a-kind background blur.


There’s not another modern lens on the market with that many aperture blades.

How can Oprema design a lens with that many blades when some of the best modern lenses on the market have 10 blades or fewer? The answer is in the Biotar’s fully manual design.

Auto-focus lenses are designed with fewer aperture blades to cut down on moving parts and reduce noise. Those are factors that the Biotar doesn’t have to worry about.


The Biotar 58 should be ready for the market in October 2018 at an expected retail price of $1,999 USD. However, backers on Indiegogo will be first in line to get this special lens.

The Biotar lens family was originally produced by Carl Zeiss in Jena, Germany and both the 58mm and 75mm classic lenses are in high demand on the vintage market.
