Overview
The Carl Zeiss Jena Biotar 58mm f/2 is the great-grandfather of modern fast normal lenses. Designed by Willi Merté in 1936, the Biotar formula became the foundation for nearly every Double-Gauss standard lens that followed — including the Planar, the Nikkor, and the Helios 44. Made in East Germany (DDR) after WWII, the Biotar carries the original Zeiss DNA before the company split. It's a living piece of optical history.
Verdict: A piece of living optical history. The Biotar isn't for pixel-peepers — it's for photographers who want character and soul. The swirly bokeh that inspired generations is here in its original form. Not practical, but utterly unique. Every lens nerd should try one.
Optical Character
Sharpness wide open
Center sharpness is good at f/4 and excellent at f/5.6-8. Mid-frame and corners are softer at wider apertures, only reaching good/very good levels at f/8-16.
Vignetting
Visible vignetting at wider apertures, improves when stopped down to f/8-11.
