The 17-70mm F2.8 VC maintains its fast F2.8 maximum aperture throughout the entire zoom range, ensuring optimal image quality even in dimly lit scenes. Its optical construction consists of 16 elements in 12 groups. By effectively incorporating two LD, two GM, and one hybrid aspherical lens elements, it achieves high resolution and high contrast not only in the center of the image but also in corners and at the edges. This advanced optical design successfully combines sharp expression that clearly captures subject details with the beautiful, soft bokeh needed to make the main subject stand out. Furthermore, it delivers exceptionally high close-up performance for a fast-aperture standard zoom lens, achieving an MOD of just 0.19m (7.5in) at the wide end and 0.39m (15.4in) at the telephoto end. This ability to get remarkably close to subjects expands your creative possibilities — whether it's creating dramatic background blur or highlighting intricate details. From everyday snapshots and tabletop photography to advanced portrait work, such versatility excels in a wide variety of shooting scenes.
