product details
The B Speed Uncoated primes are modified versions of the original B Speeds, with coatings removed to enhance flare and reduce contrast. They exaggerate all the character of the standard version of Zeiss B Speeds, and are often chosen for sequences requiring heavy atmosphere, nostalgia, or surrealism, and their imperfections are embraced as expressive tools, turning technical flaws into visual poetry. The set includes 18mm, 25mm, 35mm, 50mm, and 85mm models, all T1.4 โ offering a distinctly different look. Available for rental or sub-rental at Cine Visuals.

Zeiss B Speed Uncoated
Image Fidelity & Focus
Without coatings, these lenses produce heavy veiling glow, significantly reduced contrast, and ghosting under bright light. Painterly highlights bloom dramatically, and blacks lift, creating a hazy, nostalgic atmosphere. Sharpness is softer overall, colors are warmer, and aberrations more visible, giving images a vintage, dreamlike quality.
Handling & Adaptability
Mechanically identical to original, coated B Speeds, the uncoated versions are compact and robust. Their unpredictability requires careful lighting but offers unique expressive potential.
Flare & Bokeh
Bokeh is creamy but more chaotic than coated versions, and it sometimes glows, enhancing dreamlike rendering. Flare streaks sometimes cut through highlights.
Image Circle
Like the coated B Speeds, these lenses cover Super 35, making them widely adaptable.
Cinematic Heritage
Rental houses began offering uncoated versions of Zeiss B Speed primes in the 2000s as demand for character lenses grew and cinematographers sought new ways to push vintage looks further.
