Sigma I series Contemporary (C) lenses
Built for the streets with all-metal construction and classic manual controls.
The Sigma DG DN Art lens range has created an enviable reputation for quality optics, and it was aimed at the professional shooter looking for faster lenses with uncompromised quality. Sigma have also thought about those photographers who use full-frame mirrorless cameras and want to minimise the weight and bulk of their gear while on location. The lighter, more compact, Sigma I series Contemporary (C) range has been designed to meet those expectations. “Genuinely Made in Japan” has been SIGMA’s identity since it was founded. It shines through in every aspect of the I series, including the manufacturing, metalworking, and assembly technologies.
Sigma have been quietly expanding its I series prime lenses to cover super-wide (17mm) to telephoto (90mm) views. The range has high build quality with all-metal construction (w/metal lens hood) and the optics produce high resolution images on even the largest full-frame mirrorless sensors.
In the last couple of years, I’ve used many of the range (beginning with the 45mm) and have found them a pleasure to use, with high quality results and so easy to carry.
What follows is a brief rundown on the range and how you might apply these lenses to different subjects or photographic genres, together with some examples.
