Sensing a possibility, we put the lens into the fingers of José Francisco Salgado, knowledgeable astrophotographer, simply in time for a images journey to the Canadian sub-arctic to shoot the aurora borealis.
An necessary notice about these pattern pictures: When capturing pattern galleries for lenses, we usually preserve ISO values as little as attainable to forestall picture noise from affecting the obvious sharpness of pictures. By its very nature, astrophotography typically requires increased ISO values, even with the quickest lenses. In consequence, we requested José Francisco to seize his nighttime pictures utilizing ISO settings that have been acceptable to the situations. To permit for crucial analysis of sharpness, he additionally included a number of daytime pictures within the gallery that have been photographed at low ISO values.
What did he consider the lens? “Diagonal fisheye lenses are a part of my arsenal to seize very extensive sky topics akin to auroras and the Milky Method,” he informed us. “The Sigma 15mm F1.4 DG DN is the quickest and sharpest diagonal fisheye lens I’ve ever used.
