Sigma 18-50mm f/2.8 DC DN Contemporary Lens (FUJIFILM X)

Sigma 18-50mm f/2.8 DC DN Contemporary Lens (Fujifilm X-Mount)
The Sigma 18-50mm f/2.8 DC DN Contemporary is an exceptionally compact, lightweight, and bright standard zoom lens engineered for APS-C-format Fujifilm X-mount mirrorless cameras. Delivering a highly versatile 27-75mm full-frame equivalent focal length range and a bright, constant f/2.8 maximum aperture, this pocket-sized powerhouse is an ultimate everyday workhorse. It is perfectly optimized for a vast array of photo and video applications, including landscapes, street portraiture, architecture, travel vlogging, and event documentation.

CONDITION NOTE (GOOD CONDITION)
This lens is graded in Good condition. It shows light cosmetic signs of prior field use but is fully functional, electronically sound, and ready for deployment.

Optical Condition: There is a small amount of internal dust and minor lint visible near the front element, off to one side.

Real-World Impact: In practical field testing, this stray peripheral dust does not affect image quality, sharpness, or contrast. Photos and videos remain crisp and clear across the entire zoom range.

Included Accessories: Comes packaged complete with its front lens cap, rear lens cap, and the dedicated lens hood.

Constant f/2.8 Aperture & Premium Compact Optics
Constant f/2.8 Maximum Aperture: Maintains a bright f/2.8 exposure across the entire zoom spectrum from 18mm to 50mm. This provides excellent light-gathering capabilities for indoor or twilight shooting, alongside superior depth-of-field control for isolating subjects from busy backgrounds.

Glass-Molded Aspherical System: Features three high-precision, glass-molded aspherical elements to control geometric distortion and spherical aberrations. This complex design maximizes corner-to-corner resolution while drastically reducing the physical size and weight of the lens barrel.

Special Low Dispersion (SLD) Element: Incorporates one premium SLD glass element to eliminate secondary chromatic aberrations and color fringing, ensuring clean color accuracy and high edge-contrast.

Super Multi-Layer Coating: Optical surfaces are treated with Sigma’s proprietary multi-layer coating to suppress internal flare and ghosting, maintaining rich color neutrality when working under harsh noon sunlight or backlit staging.

Rounded 7-Blade Diaphragm: Outfitted with a circular seven-blade iris configuration that yields a smooth, circular, and highly pleasing background blur (bokeh) when shooting wide open.

Silent Stepping AF Motor & Macro Capability
Whisper-Quiet Stepping AF Motor: Driven by an agile, nearly silent stepping autofocus motor that delivers instantaneous lock-on speeds. It is optimized to support Fujifilm’s tracking algorithms, making it an ideal choice for tracking fast-moving children, pets, or pulling smooth, hunting-free focus transitions during video recording.

Impressive Macro-Style Close-Ups: Boasts a remarkable minimum focusing distance of just 4.8 inches at the wide end, paired with a maximum magnification ratio of 1:2.8. This allows you to get right up to your subject for detailed close-up food, product, or texture photography.

In-Camera Aberration Coupling: Fully communicates with Fujifilm X-series camera bodies to utilize native, on-board digital aberration corrections—instantly clearing up any residual vignetting or secondary distortion entirely in-camera.
