Irix Cine 45mm T1.5 Sony E-Mount Imperial -elokuvaobjektiivi

Prime cinema lens with a bright T1.5 aperture and 45mm focal length, built for Sony E-mount full-frame cameras. Its 9-blade rounded iris renders creamy bokeh, while the 11-element optical design ensures sharp, high-contrast imagery with minimal distortion and chromatic aberration. The lens features a robust aluminum-magnesium alloy body with weather sealing, 0.8 MOD gears on focus and iris rings, and a 180° focus rotation for precise control.

Advantages

The T1.5 maximum aperture excels in low light and provides shallow depth of field for subject isolation. The 9-blade rounded iris produces smooth, cinematic bokeh. The optical design of 11 elements in 9 groups minimizes aberrations and delivers consistent sharpness across the full-frame sensor. Very low focus breathing maintains a stable field of view during focus pulls, essential for professional cinematography. The 180° focus rotation and 75° iris rotation allow repeatable, precise adjustments. The lens is weather-sealed with 4 rubber seals, ensuring reliability in challenging environments. The 86mm front filter thread and 95mm front diameter accommodate standard cinema matte boxes and filters.

Suitable for

• Independent filmmakers and cinematographers seeking a versatile prime lens for Sony E-mount cameras.
• Documentary and commercial productions requiring a natural perspective and reliable manual focus.
• Narrative filmmaking where shallow depth of field and smooth bokeh are desired.
