Sigma full-frame Cine Prime series featuring uncoated glass elements that produce low contrast and pronounced, neutral vintage-style flares.
The Sigma Cine FF Classic Art Prime line (also called "FF Classic Prime Line") is a series of cine prime lenses for full-frame/large-format sensors, introduced at IBC in 2019 and available from early 2020. Optically, it is based on the Sigma FF High Speed Prime line but is deliberately designed for a "classic," vintage-inspired look: low contrast, warm image rendering, and pronounced, well-controllable flare/ghosting.
The core trick: While the regular Sigma Cine Primes are fully coated, only the front and rear elements of the Classic Art Primes are coated, with the remaining elements left uncoated. This means reflections and flares are not suppressed but deliberately allowed. The flares appear neutral/white and take on the color of the light source, which can be specifically colored with colored (RGB) light.
The series includes 10 prime lenses with largely uniform light intensity. Because the uncoated elements reflect more light, the T-stop is lower than with coated lenses, despite identical optical design (F1.4/F1.8).

The uniform front diameters (95 mm) and standardized gear ring positions allow for quick lens changes without repositioning follow focus, motors, or matte boxes. Via the /i Technology contacts, the lenses provide lens metadata to the camera and post-production (relevant, for example, for VFX).
Due to their strong, stylistic flares and low contrast, the Classic Art Primes are less used as universal all-round optics and are specifically chosen for music videos, dance and motion films, as well as creative commercials and corporate films. Important for lighting design: Since flares are not suppressed here, the lenses are very sensitive to direct and side light sources; the effect can be actively controlled by the position and color of the source.
Als Kameramann schätze ich an den Sigma Cine FF Classic Art Primes besonders die warme, organische Bildwiedergabe und das cremige Bokeh, das Hauttöne sehr schmeichelhaft darstellt. Die gleichmäßigen Zahnkränze und einheitlichen Frontdurchmesser machen den Objektivwechsel am Set effizient, während der charakteristische Look dem Bild eine emotionale Tiefe verleiht, die bei sterilen Optiken oft fehlt.
Diese Objektive unterstützen meine narrative Vision perfekt, da sie eine warme, filmische Atmosphäre schaffen, die besonders bei emotionalen Szenen die Zuschauer in die Geschichte hineinzieht. Der organische Character hilft dabei, eine Verbindung zwischen den Darstellern und dem Publikum zu schaffen, ohne dabei technisch aufdringlich zu wirken.
Die Sigma Cine FF Classic Art Primes bieten ein ausgezeichnetes Preis-Leistungs-Verhältnis für hochwertige Produktionen, da sie den Look teurerer Optiken zu einem Bruchteil der Kosten liefern. Die Verfügbarkeit und der moderate Mietpreis machen sie zu einer wirtschaftlich attraktiven Alternative zu High-End-Cine-Linsen, ohne dabei Kompromisse bei der Bildqualität eingehen zu müssen.
