This lens is designed with a wide T1.5 aperture, allowing for exceptional control over depth of field and enabling shooting in low-light conditions. The lens's innovative design features four high-refraction glass elements, one extra-low dispersion lens, and one aspherical lens, all contributing to the delivery of crisp details, vibrant colors, and an ultra-low distortion of just 0.5%. This lens is part of the Irix Cine line, a testament to the perfect blend of advanced technology and modern design. The 45mm T1.5 lens features a front housing element with a diameter of 95mm and a built-in 86mm filter thread.
