Robust film lens: The Irix Cine 45mm T1.5 is a cinematic lens with a focal length of 45 mm and a transmission value of T1.5. It is designed for filming in Ultra HD 8K resolution. The entire lens system consists of 11 elements arranged in 9 groups, delivering a crystal-clear image free from geometric distortions and rich in fine details. Additionally, it includes four high-refractive glass lenses, one low-dispersion lens, and one aspherical lens. This is complemented by the aperture mechanism, which features 9 rounded blades that ensure very smooth background blur and a consistent adjustment of lens brightness ranging from T1.5 to T22.

Shorter focal length: The focal length of the Irix Cine 45mm T1.5 lens is a distinctive feature. Shortened to 45 mm compared to the classic "fifty," while maintaining a natural perspective for human vision, it allows for a broader shot. Filming scenes as seen through the eyes of the character necessitates more frequent focusing, which is why the breathing effect associated with "focal length" has been minimized to an absolute minimum.
