SIGMA announces two new lenses, stretching its evergrowing range of high-end primes. The duo occupies both ends of the spectrum, with the SIGMA 500mm F5.6 DG DN OS Sports at the tele end, and the world’s first f/1.4 180° fisheye lens, the SIGMA 15mm F1.4 DG Art. Being DG DN lenses, both will come with either L-Mount or E-Mount SIGMA pushes on with its ambitious global vision. Debuted years ago with the SIGMA 35mm f/1.4 Art (recently replaced by a modern version), it has utterly transformed SIGMA’s entire brand perception. Today SIGMA produces pristine optics, some are the pinnacle of their respective field. Provocative as it may sound, I believe the access to SIGMA’s lineup was, and still is a key component in the rise of Sony’s E-Mount cameras, as well as in the success of the L-Mount alliance. Today this prominent line is growing with two additional groundbreaking lenses. Optical design Both lenses boast quite complex optical designs. The 15mm f/1.4 Art DG DN Diagonal Fisheye lens’ optical formula consists of 21 elements in 15 groups, including 4 FLD, 3 SLD, and 2 aspherical elements. this complex design enables this lens to “overturn the conventional wisdom about fisheye lenses” (in SIGMA’s words). Fisheye lenses are notoriously problematic regarding technical optical qualities. Sometimes considered to be gimmick lenses, various manufacturers didn’t put up as much effort to get their models to optical perfection. SIGMA took another path, perfecting the optical formula. As the complex formula suggests this lens opt to...
