Sony VENICE Extension System Mini Now Available: Opening New Creative Avenues for Cinematographers

It's been a long year since Sony first teased the VENICE Extension System Mini, or the CBK-3621XS as the spec sheets call it. For those of us who've wrestled full camera bodies into impossible spaces, the promise of a truly compact Rialto system was enticing. Now, after months of anticipation, the Mini is finally shipping, and it brings a suite of practical advantages that DPs (Directors of Photography) have been craving.

The original Rialto system (CBK-3610SR) for the VENICE was a significant step forward, allowing the camera's sensor block to be tethered remotely, freeing the main body from restrictive mounting positions. But it still wasn't small enough for some of the truly challenging rigs, especially in automotive work or extreme close-up scenarios. The Rialto 2 refined that, but the Mini feels like a true breakthrough in shrinking the footprint without compromising the image.

Unpacking the Mini's Form Factor

What Sony has done here is essentially distill the 8.6K full-frame CMOS sensor module from the VENICE 2 into an exceptionally tiny enclosure. The system is compatible with both VENICE 2 6K and 8K models, which is a critical point. If you've got a VENICE 2 6K, this system actually lets you capture in 8K resolution, leveraging the full potential of that separated sensor unit.

Dimensions are where the Mini truly shines. At approximately 4 inches high and 2.5 inches wide, with an E-mount attached, it's roughly the size of a large apple. Compare that to the Rialto 2, and you're looking at a 70% reduction in size. For context, the entire Sony FX3 body weighs 640 grams (1.4 lb), and the VENICE Extension System Mini with an E-mount weighs 655 grams (1.44 lb). This is a sensor block that literally weighs as much as some of the most popular mirrorless cameras on the market.

  • Compatible with VENICE 2 6K (enables 8K capture) and 8K models
  • Significantly smaller than previous Rialto systems (70% smaller than Rialto 2)
  • Weighs 655g (1.44 lb) with E-mount, 1190g (2.62 lb) with PL mount adapter

    This diminutive size isn't just about weight or general maneuverability. It's about opening up entirely new perspectives. When DP Claudio Miranda ASC discusses its utility for Formula One racing, he's touching on a core truth: when you have mere inches of clearance and need to maintain the pristine image quality of a VENICE 2, every millimeter counts. This isn't a "good enough for a stunt cam" solution; it's a "full cinema camera in an action cam's body" proposition.

    Strategic Lens Mounting and Metadata

    The Mini supports both Sony E and ARRI PL lens mounts. For the E-mount, the unit maintains its ultra-compact dimensions. However, add the PL mount adapter, and the physical size of the system almost doubles. This is a trade-off, but a necessary one, given the flange focal distance and robust mechanics required for cinema-grade PL glass.

    The PL adapter isn't just a basic mechanical conversion; it includes a 4-pin lens data port. This is key for integrating with external lens data systems (like those from Cooke /i Technology) and encoders, ensuring that critical lens metadata (focus, iris, zoom position) is captured. Metadata isn't just for VFX houses anymore; it's increasingly critical for post-production workflows, virtual production, and even on-set monitoring, providing valuable context that simplifies countless tasks down the line.

    For rigging scenarios that previously forced DPs to compromise on glass choice, the ability to utilize high-quality PL lenses on such a small sensor block is a huge advantage. This flexibility means you're not sacrificing optical quality even when the physical space is severely restricted. Imagine mounting this system onto a bespoke drone rig or a helmet cam for a truly immersive POV shot, while still maintaining the cinematic depth and resolution of a full-frame sensor and appropriate cinema glass.

    Internal NDs and User Customization

    One of the standout features directly integrated into the Mini is its nine drop-in ND filters, including a clear ND. These are automatically recognized by the VENICE 2 camera. In challenging and fast-paced shooting environments, fiddling with external ND filters is a luxury often not afforded. Having them integrated into the sensor block, especially one destined for difficult access points, is a serious design win. It means quick exposure adjustments without disturbing the rig or affecting balance.

    Beyond the NDs, the Mini provides practical user customization:

    - Two assignable user buttons (labeled 3 and 5) directly on the head

  • A 3-pin Fisher connector on the front for run/stop functionality
  • A 24V power output, useful for powering accessories like smaller focus motors or monitors

    These seemingly minor additions contribute significantly to the deployability of the system. In cramped spaces, direct control and the ability to power other necessary peripherals off the unit itself reduce cable spaghetti and simplify complex rigging setups.

    Rethinking the Cable: Detachable and Slimmer

    One of the consistent practical gripes with previous Rialto systems was the permanently attached, somewhat bulky cable. For rigging, this meant you had to guide the camera head where the cable dictated, often requiring larger openings or more complicated maneuvers.

    Sony has addressed this directly with the Mini. The system features a detachable cable plate, allowing the cable to be separated from the sensor block for rigging. Once the head is positioned, the cable can be re-attached. This might seem like a small detail, but anyone who has ever had to feed cables through tight conduits or intricate car interiors knows the value of this design choice. You only need a 2-inch gap to pass the cable through, dramatically simplifying installation.

    Furthermore, the cable itself has been redesigned. A new, slimmer cable is included, measuring 4.5 meters (14.6 feet), which is longer than the previous 3-meter (10-foot) standard and crucially, has a smaller 7.6mm diameter (down from 10.9mm). An optional 12-meter (39.37-foot) cable is also available for even more extended reach. The cable now angles straight down from the connector, preventing it from jutting out and potentially snagging or increasing the footprint of the setup. These improvements collectively make for a much more adaptable and less cumbersome rigging experience.

    Beyond the Obvious: VFX, 3D, and Virtual Production

    While the immediate benefits for tight spaces and vehicle mounts are clear, the VENICE Extension System Mini's true potential expands further into specialized production techniques. Its compact nature, coupled with the VENICE 2's image quality and metadata capabilities, makes it an attractive option for:

    - VFX Plate Capture: The ability to pack multiple sensor blocks closely together for dense camera arrays. Imaging scenarios requiring extensive VFX often benefit from capturing plate shots with pristine, high-resolution original footage, even from unusual angles. The Mini can facilitate detailed texture and light information that might otherwise be impossible to get. Leveraging Photoshop's AI Background Remover for Efficient Filmmaking Compositing

  • 3D/VR Applications: For stereoscopic capture or volumetric video, arrays of cameras have historically been bulky and complex. The Mini's size allows for tighter inter-axial distances and less intrusive setups, which could drive innovation in immersive content creation.
  • Virtual Production: As virtual production pipelines continue to mature, the precision of physical camera data is paramount. The Mini's full-frame sensor, built-in gyro, and comprehensive metadata output (via Cooke /i or a DCS external system) make it a formidable tool for capturing real-world elements for seamless integration into LED volumes or virtual sets. In a world where even minor lens distortions or inconsistencies can break immersion, having a high-fidelity image from a flexible camera head is invaluable.

    The built-in gyro sensor for metadata is another important detail. This helps in understanding camera movement and positioning with greater precision, data that is increasingly critical for complex visual effects, camera tracking, and post-stabilization workflows.

    Practical Deployment Considerations

    Any DP or 1st AC (Assistant Camera) knows that new gear, no matter how exciting, comes with its own set of production considerations.

    - Heat Management: Sony has clearly considered this, incorporating air inlets on the sides and an exhaust outlet on top to dissipate heat from the sensor block. Miniaturizing powerful imaging components always presents thermal challenges, and adequate cooling is crucial for maintaining image quality and sensor longevity, especially in high-temperature environments.

  • Durability: While the unit is encased in aluminum, its intended use cases (cars, stunts, tight rigs) inherently mean it will be subjected to more bumps and jostles than a camera on a tripod. Long-term reliability in these harsh conditions will be key to its widespread adoption.
  • Cabling Complexity: While improved, managing the power, data, and video signals for a separated sensor head still requires careful planning. The extended cable lengths offer flexibility, but also necessitate robust cable management on set to prevent snags and ensure signal integrity.
  • Cost-Benefit Analysis: This is a premium solution, designed for the high-end productions that typically utilize the VENICE 2. Filmmakers will need to weigh the creative and logistical advantages against the rental or purchase costs, understanding that the value lies in enabling shots that would otherwise be impossible or prohibitively expensive to achieve with a full camera body.

    The VENICE Extension System Mini, in its essence, represents Sony's continued commitment to providing high-fidelity imaging solutions that adapt to complex creative demands. It’s a tool that doesn't just promise flexibility, but delivers it by shrinking the unshrinkable (the full-frame sensor) into a package that makes DPs reconsider what's truly possible. For productions wrestling with ambitious shots in constricted environments, this Mini solution could be the missing link.
