Sigma 17-35mm F/2.8-4 EX Aspherical Autofocus Lens For Pentax K Mount (USED)
The Sigma 17-35mm f/2.8-4 EX Aspherical is a versatile, ultra-wide-angle zoom designed for photographers who need high-end "EX" (Excellence) performance without the massive price tag of a first-party Canon L-series lens. Whether you’re shooting on a modern Full-Frame DSLR or an APS-C body, this lens provides a dramatic perspective that is perfect for everything from tight interiors to expansive landscapes.
The "EX" Advantage: Professional Build
As part of Sigma’s EX series, this lens was built to a higher standard than their consumer-grade glass. It features a rugged, matte finish and a solid mechanical feel.
-
Aspherical Optics: The lens incorporates molded glass aspherical elements in both the front and rear groups to correct spherical aberration and distortion—critical for ultra-wide-angle photography.
-
Internal Focusing (IF): The lens barrel doesn’t change length during focusing, and the front element doesn’t rotate. This makes it incredibly easy to use with circular polarizers or the included petal-shaped lens hood.
