SIRUI Vision Prime 1 Series 75mm T1.4 Full Frame Cine Lens — Full Frame 75mm T1.4 Mid-Telephoto Cine Lens, 270° Focus Throw, User-Swappable Mount

The SIRUI Vision Prime 1 Series 75mm T1.4 is a prime lens built for filmmaking. Its 75mm focal length is a mid-telephoto — a popular choice for portrait, fashion and animal photography — delivering natural compression and soft bokeh that separates the subject from the background. The fast T1.4 aperture gathers plenty of light even in dim conditions, creating shallow depth of field and soft, round light orbs. Designed for cine work, focus and iris respond smoothly and naturally, with standard 0.8 MOD gears and a 270° focus throw. Aspherical + ED + HRI Glass elements control distortion and chromatic aberration for sharpness from center to edge. The Interchangeable Mount system supports Sony E / Canon RF / Nikon Z / Leica L in a single lens. Aluminum Alloy body, approx. 700 g.

FAQ

• Q: Can I really change the mount myself?
  A: Yes. The lens ships with a factory-fitted Sony E mount, and Canon RF / Nikon Z / Leica L mount modules are included in the box. You can swap them yourself without shimming.
• Q: What is the difference between T-stop and F-stop?
  A: A T-stop measures the actual amount of light transmitted through the lens, including losses from the glass elements and coatings, while an F-stop is a theoretical value. Filmmakers use T-stops so exposure matches across every lens in a set.
• Q: Does the 75mm work in tight spaces?
  A: You need a fair amount of distance from the subject, so a small room can feel cramped. It is best used in larger spaces or outdoors. For tight spaces, the 15mm or the 24/35mm in the same series would suit better.
