Sirui Vision Prime 1 Series 50mm T1.4 Cine Lens - Sony E Mount - Metal Grey

Yes, the lens comes with interchangeable mount adapters for Nikon Z, Canon RF, and L-mount systems, significantly broadening its compatibility.

Minimal focus breathing means that the field of view changes very little when you adjust the focus. This is crucial for smooth, professional-looking focus pulls during video recording, preventing distracting "zooming" effects.
