Sony LA-FZB2 User Manual

The Sony LA-FZB2 is a lens mount adapter specifically designed to bridge the gap between Sony’s FX6 and FX9 cameras (E-mount) and B4-mount lenses commonly used in broadcast and studio environments. This adapter allows FX6 and FX9 users to leverage their existing HD or even BOX-type lenses typically used with studio cameras, for Full-Frame cinematography.

Key Features:

• B4 Mount to E-Mount Compatibility: The LA-FZB2 enables the use of B4-mount lenses on Sony’s FX6 and FX9 professional cameras with E-mounts. This opens up a wider range of lens options for these cameras, potentially saving costs by allowing you to utilize existing lenses for Full-Frame film projects.
• Maintains Field of View: The adapter is designed to preserve the original field of view that the B4-mount lens offers on a 2/3″ prism block camera. This ensures you capture the intended image without cropping or alteration of the focal length.
• Data Communication: The LA-FZB2 facilitates two-way communication between the B4 lens and the FX6/FX9 camera. This allows for features like iris control, focus information display in the viewfinder, and potentially lens aberration data transfer for in-camera correction (with compatible lenses).
• Clear Image Zoom: The LA-FZB2 works in conjunction with Sony’s advanced Clear Image Zoom technology within the FX6 and FX9 cameras. This allows for high-quality zoomed-in shots while maintaining a 4K resolution output, effectively extending the focal range of your B4 lenses.
• Compact and Lightweight Design: Despite its functionality, the LA-FZB2 is surprisingly small and lightweight (approximately 89 x 180 x 85 mm and 0.8 Kg). This makes it easy to handle and helps maintain a good balance on the FX6/FX9 cameras.

Things to Consider:

• Compatibility: While the LA-FZB2 works with Sony’s FX6 and FX9 cameras, it’s not universally compatible with all B4-mount lenses. Sony recommends checking their documentation or contacting a professional to ensure compatibility between the specific B4 lens you intend to use and the LA-FZB2 adapter.
• Full-Frame vs. HD Capture: The LA-FZB2 allows leveraging existing HD B4 lenses on FX6 and FX9 cameras that offer Full-Frame sensors. However, it’s important to understand that the adapter doesn’t inherently upscale the image quality of the B4 lens itself to true Full-Frame resolution. You will be capturing an HD image inside the larger Full-Frame sensor.
• Potential Image Quality Limitations: B4 lenses designed for HD capture may not perform optimally when used for Full-Frame filmmaking. There might be a slight softness or limitations in capturing fine details compared to native Full-Frame lenses.
• Alternative Lens Options: Sony offers a variety of native E-mount lenses specifically designed for Full-Frame cinematography with the FX6 and FX9 cameras. These lenses may provide superior image quality, wider aperture options, and better low-light performance compared to using an adapter with B4 lenses.

Overall, the Sony LA-FZB2 is a valuable tool for Sony FX6 and FX9 camera users who want to expand their lens options or utilize existing B4-mount lenses for Full-Frame projects. The adapter offers compatibility, data communication, Clear Image Zoom support, and a compact design. However, compatibility verification, potential image quality limitations with B4 lenses, and availability of native Full-Frame lens options are important factors to consider before purchasing the LA-FZB2.
