This news is primarily being outed via a Kickstarter update that the company made. It states specifically:
“The Biotar 75 is a great lens, deriving from a great family. As we told you, our technical engineers Wolf-Dieter Prenzel and André de Winter have already plans to revive the famous Biotar 58 mm and the Flektogon lenses.
With the 58mm becoming available as prototype very soon, we want you to get the chance to get your hands on the Biotar 58mm already at an early stage. Therefore we have added a pledge which includes the Biotar 58mm and the Biotar 75mm as a bundle. “
We can assume that these lenses are going to be made of metal and will have something of a special bokeh.
I’m a former owner of the original Zeiss 58mm f2 Jena Biotar lens and they were incredible. Bellamy Hunter tells me that most of the lenses are known to have bubbles because of the lack of quality control–but if you happen to get your hands on one that doesn’t have bubbles, then you’re in luck. My buddy Horatio Tan recently played with a 75mm f1.8 Biotar without bubbles, and it’s images super sharp and gorgeous. The original 75mm f1.8 Biotar lenses are going for a lot of money.
Below are images shot with my original Jena Biotar 58mm f2–hopefully the lens will be up to standard; and I’m sure it will be.
