This professional-grade, high-precision all-metal adapter is engineered to mount industry-standard B4 mount (2/3" format) broadcast/cine ENG lenses onto Sony E mount full-frame and Super 35mm (APS-C) mirrorless and cinema cameras. Its robust 210g all-metal construction is designed to securely support heavy professional broadcast lenses, providing an extremely stable, play-free connection and ensuring precise infinity focus. It effectively bridges the gap between professional broadcast optics and Sony's powerful digital imaging ecosystem, greatly expanding the creative and practical applications of B4 lenses.
Critical Note:B4 lenses are designed for a 2/3" image circle and will project a circular image. On Sony full-frame cameras, this results in heavy circular vignetting (black borders). It is strongly recommended to pair with Sony Super 35mm/APS-C cameras (e.g., FX30, A6700) for optimal image coverage.
· Professional Heavy-Duty Metal Build:Constructed from precision CNC-machined chrome-plated brass and stainless steel, weighing 210g for maximum durability. Optimized for the professional B4 interface, it ensures a rock-solid, zero-play connection for demanding production environments.
· Ensures Precise Infinity Focus:Meticulously engineered to the exact flange distances of both B4 and Sony E mounts, guaranteeing accurate infinity focus and preserving the optical performance of your broadcast lens.
· Compatible with Professional B4 Lenses:Perfectly adapts standard B4 mount broadcast/cine lenses, including models with servo zoom, power aperture, and optical stabilization features (note: auto functions require lens power/internal control).
· Extensive Camera Compatibility:Compatible with virtually all Sony E mount cameras, enabling innovative use of professional B4 lenses on Sony full-frame, Super 35mm, and cinema camera systems like the FX6, FX3, BURANO, and VENICE 2.
· Integrates into Professional Workflows:A purely mechanical adapter, it requires manual control of aperture, focus, and zoom. It serves as a crucial bridge for integrating high-quality, cost-effective broadcast lenses into Sony E-mount workflows for multicam live production, studio work, documentary, and creative filmmaking.
· Lenses:Standard B4 mount broadcast/cine ENG lenses (designed for 2/3" image circle).
· Cameras:All Sony E mount cameras, especially Super 35mm/APS-C models like the FX30, A6700, A6600, A6400, ZV-E10 II, as well as full-frame/cinema models like the A7CR, FX3, FX6, BURANO, and VENICE 2 (with significant cropping/vignetting on full-frame).
