Ultra Fast F1.2 Maximum Aperture
The Viltrox AF 27mm F1.2 PRO E features an industry-leading F1.2 maximum aperture, enabling exceptional light-gathering capabilities and ultra-shallow depth of field. This allows for clean subject separation and beautiful bokeh, even in dimly lit environments. The large aperture also supports faster shutter speeds for action and low noise at high ISO settings.This empowers photographers and videographers to achieve cinematic backgrounds and outstanding low light performance in any setting.
Advanced Autofocus with STM Motor
Equipped with a high-precision stepping motor (STM), this lens delivers fast, accurate, and near-silent autofocus, making it ideal for both stills and video applications. The autofocus system is optimized for Sony E-mount cameras, supporting real-time Eye AF and subject tracking, even at wide apertures. Compared to earlier Viltrox models, AF acquisition is notably quicker and more reliable.This ensures sharp, in-focus shots for dynamic subjects and seamless focus transitions in video production.
Professional-Grade Optical Construction
The optical formula incorporates 11 elements in 9 groups, including 2 aspherical and 2 extra-low dispersion (ED) elements, significantly reducing chromatic aberration and distortion. Multi-layer nano coatings enhance contrast and suppress flare, ensuring clarity in high-contrast or backlit scenes. The lens is designed to maximize the resolving power of modern high-resolution sensors.This results in edge-to-edge sharpness and color fidelity, crucial for commercial and editorial work.

Weather-Sealed, Durable Build
The Viltrox 27mm F1.2 PRO E boasts a robust, all-metal barrel with comprehensive weather sealing at critical points, protecting against dust, moisture, and light rain. The construction quality rivals that of native Sony G and GM series lenses. Its durability ensures consistent operation in demanding outdoor conditions.This allows professionals to shoot confidently in variable weather, from urban streets to remote landscapes.
Versatile 27mm APS-C Focal Length
Offering a 40.5mm full-frame equivalent field of view, the 27mm focal length is highly versatile for everyday photography, street, documentary, and environmental portraiture. The natural perspective closely matches the human eye, making compositions intuitive and immersive. Compared to traditional 35mm or 50mm primes, this focal length provides a unique balance between wide and standard views.This makes it an ideal single-lens solution for creators who value flexibility without lens swaps.
Rounded 11-Blade Diaphragm for Smooth Bokeh
The lens utilizes an 11-blade rounded diaphragm that produces pleasingly smooth, circular bokeh highlights, even when stopped down slightly. This design minimizes onion-ring bokeh and maintains background separation in portraits and close-ups. Bokeh quality is competitive with premium Sony and Sigma ART lenses.This enhances creative expression by rendering backgrounds beautifully out of focus, perfect for subject isolation.
Customizable Aperture Ring with De-Click Option
A dedicated aperture ring allows tactile, manual control over F-stop settings, with a de-click function for smooth, silent adjustments during video recording. The ring features precise detents and a lock switch to prevent accidental changes. This is a rare feature at this price point, especially among third-party lenses.This gives cinematographers and hybrid shooters intuitive exposure control without menu diving.
Short Minimum Focusing Distance
With a minimum focusing distance of just 0.28m (11 inches), the lens enables semi-macro shooting for close-up details, food, and product photography. The large aperture further enhances subject-background separation at close distances. Compared to older Viltrox primes, the close focus capability is improved for more creative options.This lets users capture intimate details and creative perspectives in everyday scenes.
Optimized for High-Resolution Sensors
Engineered to resolve over 50 megapixels, the Viltrox 27mm F1.2 PRO E maintains image sharpness and micro-contrast on the latest Sony APS-C cameras. Edge-to-edge clarity and minimal optical aberrations ensure files are suitable for large prints and commercial use. It competes directly with native Sony G and Sigma Contemporary lenses in resolving power.This guarantees professional results for demanding applications like advertising, fine art, and editorial work.
USB-C Firmware Upgrade Port
A built-in USB-C port allows easy firmware updates, ensuring compatibility with future Sony camera bodies and autofocus improvements. Viltrox regularly issues firmware enhancements to refine AF algorithms and expand compatibility. This forward-thinking feature is unique among most third-party lenses.This future-proofs your investment and keeps the lens performing optimally with evolving camera technologies.
Lightweight, Balanced Handling
Despite its robust build, the lens weighs just 560g (1.23 lbs), providing excellent balance on Sony APS-C mirrorless bodies. The compact form factor and ergonomic focus ring make it comfortable for long handheld sessions. Compared to similar F1.2 primes, it is lighter and less front-heavy.This reduces fatigue during extended shoots and makes it practical for gimbal or travel use.
