Features on this zoom include a constant f\/1.8 aperture throughout the zoom, a redesigned Hyper Sonic Motor (30% slimmer) and the same high-level of engineering that produces the same angle-of-view, shallow depth-of-field and light gathering capabilities. F1.8 on APS-C gives you around the depth-of-field control of F2.7 on full-frame. That makes Sigma's 18-35\/1.8 and 50-100\/1.8 roughly equivalent to 27-53\/2.7 and 75-150\/2.7 lenses on full-frame, in terms of both DOF and noise (in low light) control. For some photographers, this lens will go a long way in addressing some of the inherent disadvantages of the smaller sensor format. Complementing the imaging capabilities is a refined physical construction with internal focus and zoom mechanisms to limit the overall length of the lens during use. The ability to maintain focus along with a Hyper Sonic that provides bright and accurate AF throughout the entire range, this Sigma 50-100mm F1.8 zoom lens is also ideal for videographers.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eArt Line Series Zoom\u003c\/b\u003e\u003c\/p\u003e\n\n\u003cp\u003eAs 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eIncreased Versatility\u003c\/b\u003e\u003c\/p\u003e\n\n\u003cp\u003eImpressively fast f\/1.8 constant maximum aperture benefits working in difficult lighting conditions throughout the zoom range and also offers increased control over focus when working with selective focus techniques.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eProvides Impressive Sharpness and Contrast\u003c\/b\u003e\u003c\/p\u003e\n\n\u003cp\u003eThree F Low Dispersion elements and one Special Low Dispersion element markedly reduce chromatic aberrations and color fringing throughout the zoom range.
