  • It is desirable to provide an optical system that is lightweight, easy to handle, and has high optical performance across the entire screen, and an imaging device equipped with such an optical system.
  • [Background Art]
    [0002]
    In recent years, the number of pixels in the image sensors used in interchangeable lens digital camera systems has been increasing, and optical systems are being required to provide correspondingly high image quality. In addition, small and lightweight camera bodies are the norm for the interchangeable lens mirrorless cameras that have become popular in recent years, and optical systems are being required to be smaller and lighter, and such optical systems have been developed (see Patent Document 1).
  • [0004]
    On the other hand, telephoto lenses compatible with large image sensors such as full-size sensors generally end up being large in size, so the optical system is required to have a weight balance with the center of gravity close to that of the camera body, which is suitable for small, lightweight camera bodies in terms of maneuverability.
  • It is desirable to provide an optical system that
    is lightweight, easy to handle, and has high optical performance over the entire screen, and an imaging device equipped with such an optical system.

Viltrox 35mm f/1.2 LAB Announced

By Louis Ferreira | Published: April 16, 2025


Viltrox 35mm f/1.2 LAB: B&H Photo / Amazon

Viltrox announced the Viltrox 35mm f/1.2 LAB, which we have been covering for quite a while.


1. HyperVCM Motor: Speed Meets Precision
Powered by Viltrox’s proprietary HyperVCM motor, the lens achieves 150% faster focus than traditional STM systems, with micron-level accuracy and lightning-fast 100ms near-far focus transitions. Ideal for capturing fleeting moments in portraits, events, or dynamic video work.


2. Flagship Optical UA Lens Design
With Ultra-Large & Precision Aspherical Elements, the lens delivers edge-to-edge clarity even at its blazing-fast F1.2 aperture. Designed for ultra-high-pixel sensors, it resolves intricate textures—skin pores, hair strands, fabric weaves—with stunning fidelity, whether shooting close-ups or infinity landscapes.


3. F1.2 Ultra-Large Aperture: Master of Bokeh
Create cinematic depth with lush, dreamy backgrounds and pristine highlight rendering. The F1.2 aperture isolates subjects effortlessly, transforming chaotic scenes into gallery-worthy compositions—perfect for portraits, astrophotography, or low-light storytelling.


4. Macro to Infinity: Seamless Sharpness
A 0.34m minimum focus distance and 0.17x magnification unlock macro capabilities, while the dual floating internal focus system ensures real-time aberration correction. Edge-to-edge sharpness remains consistent from intimate close-ups to sweeping vistas.


5. Advanced Optical Construction
14 elements in 9 groups—including 2 UA lenses, 5 low-dispersion elements, and 3 high-refractive-index elements—combat chromatic aberration and flare. Even in harsh lighting, the lens maintains premium color accuracy, dynamic contrast, and near-zero purple/green fringing.

6. Pro-Grade Customization

  • 2 customizable Fn buttons for instant access to frequently used settings.
  • Multi-function control ring with click/clickless switch for silent video adjustments.
  • AF/MF switch for tactile control.

 

Technical Specifications

  • Mount: Sony E-mount (FE)
  • Aperture: f/1.2 – f/16 | Blades: 11 rounded
  • Filter Thread: 77mm | Weight: 920g
  • Angle of View: 64.2° | Focus System: Dual floating internal focus
  • Build: Dust- and moisture-resistant
