Product Overview +
Go Small, Shoot Big with 8.6K Precision
The Sony CBK-3621XS (VENICE Extension System Mini) is engineered to deliver next-generation visual content in a radically compact form factor. By integrating the 8.6K full-frame sensor directly into the miniaturized camera head, it preserves the elite image quality of the VENICE 2 while offering a volume reduction of 70% over previous extension systems. This enables VENICE 2 6K users to upgrade their capabilities to 8.6K acquisition when using V4.0 firmware.
Revolutionizing Specialized Cinematography
Designed for the most demanding creative setups, the Extension System Mini transforms stereoscopic, 360° VFX plate, and stitch shooting. Its small footprint ($63.9 \times 103.2 \times 60.2\text{ mm}$) allows two head blocks to be placed side-by-side for natural stereoscopic imagery or clustered for virtual production background filming. The detachable, flexible cabling ensures that cinematographers in Pakistan, the UAE, and Africa can navigate tight spaces and complex rigs without compromising signal integrity.
Professional Reliability in Any Environment
The CBK-3621XS is built for stable performance, featuring a robust design resistant to dust, moisture, and shocks. A built-in cooling fan manages heat during high-frame-rate recording—consuming a maximum of approximately $15\text{W}$ during 5.5K 120FPS operation. With support for both PL and E-mount lenses and fine-tune flange back adjustment, this system offers the ultimate toolset for high-end cinematic expression.
