Sigma 18-35mm f/1.8 DC HSM Art Lens for Canon EF 商品介紹

Sigma 18-35mm f/1.8 DC HSM 以其獨特的快速和多功能設計而著稱,是一款藝術系列變焦鏡頭,涵蓋廣角到正常焦距。這款變焦鏡頭與眾不同,具有極其明亮的 f/1.8 恆定最大光圈,適合在惡劣的照明條件下使用,並在整個變焦範圍內提供令人印象深刻的景深控制。光學設計融合了一系列 SLD 和非球面鏡片,通過抑制各種像差、色邊和失真,有助於實現高清晰度和銳度。還應用了超級多層塗層,它可以控製鏡頭眩光和鬼影,以提高對比度和色彩準確性。平衡光學優點,這款 18-35mm 還採用先進的超音速馬達,以及內部對焦設計,以提高快速、安靜和精確的自動對焦性能。

作為適馬 Global Vision 系列中藝術系列的一部分,這款鏡頭旨在實現真正顯著的光學性能,非常適合創意和藝術應用。

廣角變焦專為 APS-C 格式相機設計,提供 28.8-56mm 等效焦距範圍。

令人印象深刻的明亮恆定 f/1.8 最大光圈非常適合在弱光條件下工作,並且在使用淺景深技術時還可以更好地控制焦點位置。

光學設計中採用了五個特殊的低色散 (SLD) 元件,有助於減少色邊和色差,從而提高清晰度和色彩準確度。

四個非球面元素用於幫助限制失真和球面像差,還有助於提高整體清晰度和準確渲染。

超級多層鍍膜已應用於鏡頭元件,以最大限度地減少鏡頭眩光和鬼影,並有助於產生對比度豐富和色彩中性的圖像,即使在背光條件下也是如此。

集成 HSM(Hyper Sonic Motor)以及內部對焦系統,可實現快速安靜的自動對焦,並輔以優化的自動對焦算法,以產生更流暢的對焦性能。 HSM 還允許隨時通過旋轉對焦環進行全時手動對焦控制。

圓形九葉片隔膜有助於實現平滑和令人愉悅的散景質量。

採用熱穩定複合 (TSC) 材料製成,具有更高的精度並適用於廣泛的溫度變化。此外,黃銅卡口可提高安裝精度和剛度。

該鏡頭與可選的 Sigma USB Dock 兼容,用於微調不同的鏡頭特性並更新其固件。

產品規格

  • Canon EF-Mount Lens/APS-C Format
  • Focal Length: 28.8-56mm (35mm Equivalent)
  • Aperture Range: f/1.8 to f/16
  • Five SLD Elements
  • Four Aspherical Elements
  • Super Multi-Layer Coating
  • Hyper Sonic Motor AF System
  • Rounded 9-Blade Diaphragm
  • As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
  • Wide-to-normal zoom is designed for APS-C-format Canon EF-mount cameras and provides a 28.8-56mm equivalent focal length range.
  • Impressively bright constant f/1.8 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.
  • Five Special Low Dispersion (SLD) elements are featured in the optical design and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy.
  • Four aspherical elements are used to help limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering.
  • A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
  • Integrated HSM (Hyper Sonic Motor), along with an internal focusing system, realizes quick and quiet autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.
  • Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
  • Constructed using a Thermally Stable Composite (TSC) material for greater precision and use in wide temperature variations. Additionally, a brass bayonet affords improved mounting accuracy and rigidity.
  • This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
  • In the Box: Sigma 18-35mm f/1.8 DC HSM Art Lens, Sigma LCF-72 III 72mm Lens Cap, Sigma Rear Cap LCR II, Sigma Lens Hood for 18-35mm f/1.8 Art DC HSM Lens, Lens Case
