Rent NowRokinon AF 18mm f/2.8 FE Lens (Sony E-Mount)
Ultra-Wide, Lightweight Rectilinear Prime for Full-Frame Mirrorless Systems
The Rokinon AF 18mm f/2.8 FE is an exceptionally compact and featherlight ultra-wide-angle prime lens designed natively for full-frame Sony E-mount mirrorless cameras. Delivering a dramatic rectilinear field of view, this lens keeps straight lines straight, making it an outstanding choice for sweeping landscapes, architectural marvels, tight real estate interiors, and travel photography.
By balancing an ultra-wide perspective with a highly efficient f/2.8 aperture, Rokinon has engineered an incredibly portable, pocket-sized prime that delivers edge-to-edge sharpness and clarity. Its lightweight footprint also makes it a perfect choice for use on compact travel gimbals, drones, and lightweight astrophotography star-tracker rigs.
Advanced Specialized Optics & Aberration Suppression
Dramatic Rectilinear Ultra-Wide View: Captures vast, immersive compositions natively on full-frame Sony bodies while correcting geometric distortion to ensure straight architectural columns and horizons remain perfectly linear. It can also be paired with crop-sensor APS-C Sony cameras, providing a comfortable 27mm equivalent wide-angle perspective.
Three Extra-Low Dispersion (ED) Elements: Incorporates three specialized ED glass elements to systematically stamp out color fringing and chromatic aberrations, resulting in high clarity, fine texturing, and accurate color rendering.
Three Aspherical & Two HR Elements: Features an advanced optical layout containing three aspherical elements paired with two High Refractive Index (HR) components to correct field curvature, suppress spherical aberrations, and deliver uniform resolution from the center to the corners of the frame.
Ultra Multi-Coating (UMC) Flare Defiance: Individual lens components are treated with a multi-layer Ultra Multi-Coating. This layer actively minimizes surface reflections, internal ghosting, and lens flare to protect image contrast and preserve a completely neutral color balance under harsh lighting.
Snappy Linear STM AF Motor & Internal Focusing
Linear STM Stepping Autofocus Motor: Outfitted with a high-torque linear STM stepping focus motor that integrates seamlessly with Sony’s advanced camera autofocus algorithms. It delivers rapid, pinpoint, and near-silent focus acquisition for both high-speed stills and fluid video tracking.
Full-Time Manual Focus Override: Features full-time manual focus override capabilities, allowing you to instantly grab the focus ring to make critical, micro-adjustments without needing to navigate on-screen setting toggles.
Stationary Internal Focusing (IF) Engineering: Built with an advanced internal focus matrix that ensures only internal lens groups move during focus tracking. The physical length of the barrel remains completely stable, speeding up response times and preventing the front 58mm filter thread from rotating when utilizing specialized circular polarizers.
Flippant Available-Light Speed: The f/2.8 maximum aperture successfully strikes the ideal balance between low-light speed and structural portability, letting you shoot handheld in mixed available light while keeping the lens body under 6 ounces.
