Samyang 85mm f/1.4 Aspherical IF Lens (Sony E)
Manual Focus Portrait Telephoto Prime – Bright f/1.4 Maximum Aperture, 85mm Focal Length (127.5mm APS-C Equivalent), Internal Focusing (IF) Mechanism (Non-Rotating Front 72mm Filter Thread), Advanced Optical Design with One Hybrid Aspherical Element, Ultra Multi-Coating (UMC), 8-Blade Rounded Diaphragm, Smooth Damped Manual Focusing Ring, Native Full-Frame & APS-C Sony E-Mount (Good Condition)
The Samyang 85mm f/1.4 Aspherical IF is a classic manual-focus portrait telephoto prime engineered for full-frame Sony E-mount mirrorless cameras (also functioning as an intimate 127.5mm equivalent portrait lens on APS-C format bodies). Designed for portrait artists, fine-art shooters, and low-light cinematographers seeking shallow depth of field, this lens pairs an ultra-fast f/1.4 maximum aperture with precise tactile manual operation. The f/1.4 maximum aperture affords superior light transmission in dimly lit environments while enabling dramatic subject isolation, rendering creamy, cinematic background blur with smooth focus falloff.
The optical formula utilizes 9 elements in 7 groups, incorporating one high-precision hybrid aspherical element to curb spherical aberrations, chromatic fringing, and geometric distortion. All optical glass surfaces feature Samyang’s proprietary Ultra Multi-Coating (UMC) to suppress ghosting and surface reflections while maintaining rich contrast and neutral color fidelity. The lens utilizes an Internal Focusing (IF) design, which ensures the physical barrel length remains constant throughout the focus throw and prevents the front 72mm filter thread from rotating—simplifying the use of circular polarizers and variable ND filters. Built with an 8-blade rounded diaphragm for natural, pleasing out-of-focus specular highlights and an all-metal bayonet mount, this fast portrait prime offers classic manual optical rendering in good working order.
CONDITION DIAGNOSTICS & PHYSICAL NOTES
Included Components: SOLID MANUAL TELEPHOTO PRIME. Supplied with the Samyang 85mm f/1.4 Aspherical IF lens, front snap-on lens cap, and rear Sony E-mount protective cap. (Lens hood, camera bodies, and screw-in filters sold separately unless pictured).
Exterior & Barrel Status: GOOD CONDITION. The matte black textured barrel, ribbed rubber manual focus grip band, aperture ring, and metal bayonet mount show typical cosmetic signs of standard field handling, including light surface scuffs and minor finish rub marks along the outer chassis contours. All engraved distance scales (in feet and meters), depth-of-field markings, and bright red aperture numbers remain clean, sharp, and fully legible.
Optical Status: FAIR TO GOOD CONDITION. Front and rear external glass surfaces are free of deep scratches, gouges, chips, or fungus. The internal optical assembly contains minor scattered dust specks alongside visible light haze localized behind the front element group; bench evaluation and test exposures indicate that standard resolution and center sharpness remain well preserved, though the internal haze may produce a mild reduction in micro-contrast or introduce a subtle softening glow when shooting wide open directly into harsh, unshaded backlighting.
Mechanical & Aperture Status: FULLY FUNCTIONAL. The wide rubberized manual focus ring rotates smoothly with consistent, well-damped mechanical resistance across the entire focus throw; the internal focusing (IF) mechanism shifts internal groups cleanly without binding; the manual aperture ring clicks positively into all detents from f/1.4 through f/22; the 8-blade rounded diaphragm actuates crisply and closes down evenly with zero oil contamination or sluggishness; the solid metal E-mount bayonet seats firmly onto Sony camera mounts without lateral play.
KEY FEATURES & PERFORMANCE HIGHLIGHTS
Fast f/1.4 Maximum Aperture: Excels in demanding low-light environments and yields razor-thin depth-of-field control with soft, cinematic background separation.
Versatile Full-Frame & APS-C Reach: Serves as a standard 85mm portrait length on full-frame cameras, providing an extended 127.5mm telephoto perspective on Sony APS-C crop sensors.
Precision Internal Focus (IF) Mechanism: Focuses entirely internally, keeping the overall barrel length fixed and preventing the front 72mm filter thread from spinning.
Hybrid Aspherical Glass Element: Minimizes spherical aberrations and optical distortion to deliver sharp central resolution across wide aperture settings.
Ultra Multi-Coating (UMC): Reduces internal lens reflections, flare, and ghosting, preserving natural color neutrality and shadow contrast.
8-Blade Rounded Diaphragm: Engineered with 8 curved blades to produce smooth, circular out-of-focus background highlights and pleasing bokeh transitions.
Fully Mechanical Control: Provides a long-throw, tactile manual focusing experience paired with a click-stopped manual aperture ring, ideal for both stills and video rigs.
Non-Rotating 72mm Filter Thread: Facilitates easy use of specialized polarizers, variable neutral density filters, and matte boxes without alignment shifts during focusing.
