SIRUI IronStar T1.9 1.5x Anamorphic Full Frame Cine Lenses 45mm(Blue Flare)
The SIRUI IronStar T1.9 1.5× Anamorphic Full Frame Cine Lenses 45 mm (Blue Flare) is a professional full-frame cinema lens suitable for demanding film productions with high requirements for perfect appearance, maximum luminosity and durable construction. The IronStar series combines high quality optics, precision mechanics and professional film design and is compatible with PL or EF bayonets. With a 1.5x anamorphic ratio, you get a characteristic widescreen image with an aspect ratio of 2.66:1 with a 16:9 sensor or 2.25:1 with a 3:2 sensor. The extremely luminous T1.9 aperture allows shooting in low-light conditions with strong separation of the subject from the background and a deep, subtly oval bokeh effect. The SIRUI IronStar T1.9 1.5× Anamorphic Full Frame Cine Lenses 45 mm lens delivers excellent microcontrast, minimal optical defects (aberrations) and subtle, controlled flare in the Blue Flare variant. The lens is suitable for use on RED, ARRI Alexa Mini, Blackmagic URSA Mini Pro, Canon C-Series and other full-frame cinema cameras.
