Sigma 14/1.8 Art
« on: August 01, 2017, 11:09:26 AM »
The legacy if the Sigma Art prime lenses created great expectations for me as professional Astronomer when the new 14mm incarnation arrived! A trip to the dark Carinthian Alps under a 21.7mag/"² sky allowed a first comparison with the Canon EF 14/2.8 II prime I used before! I think the result is clear ... A widefield dream come true! All comparison pics are ordered the same way, upper row Canon, lower Sigma, always with the aperture sequence 1.8/2.8/4.0 with exposure times leading tho the same exposure level. The fist pic compares vignetting, the second the centre region, the third the upper left corner and then there are two astro pics, one 20 second single shoot and then a 6 pics stack of 30 second pics...
