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.
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.
Visible vignetting at wider apertures, improves when stopped down to f/8-11.
Summary: The community has a mixed sentiment towards the Helios 58mm lens, with some users reporting it as an amazing value for money Zeiss Biotar equivalent, while others finding it to be a "worthless paperweight." The lenses seem to vary significantly in terms of sharpness and flare characteristics, with some models being preferred for their unique artistic qualities. Sentiment: Mixed Top Praised: - Unique flare characteristics that can be desirable for certain projects - Potential for Zeiss Biotar-like image quality in some models - Affordability compared to modern lenses Top Complaints: - Inconsistent quality, with some models being significantly softer than others - Unpredictable flare behavior, which may be a flaw for some users - Potential for lenses to be "worthless" if they don't meet expectations Use Cases: - Vintage/film-like aesthetic, especially when using wide-open apertures - Artistic projects where unique flare patterns are desirable - Budget-conscious filmmaking or photography where a Zeiss-like look is sought Disagreements: - There seems to be a divide between users who see the lens as a valuable tool and those who consider it a "paperweight" Confidence: 0.8
