Sigma C 18-50 mm f/2.8 DC DN – first impressions and sample images
1. Introduction
Of course I am joking and deliberately going over the top but it doesn't change the fact that I like smaller sensors. The APS-C format is, in my opinion, a very sensible solution, offering you an excellent image quality while allowing you to construct small, shapely, lightweight optics and camera bodies.
Because of my views, unworthy of a professional, I do regret so few companies treat smaller sensors seriously. Nikon tried to do so at the beginning of the digital era - it lasted only up to a point, ending when they got an access to full frame sensors.

After a launch of mirrorless cameras the situation changed just slightly. Only Fujifilm tackled the topic of smaller sensors, offering a very successful X system. Sony got engaged seriously at first, but when they launched full frame optics they put both lenses and bodies designed for APS-C sensor in second place. The Canon EF-M, after a decade of presence on the market, can offer you just eight lenses, one fast prime among them. When Nikon got rid of the madness called Nikon 1 system, they started to develop DX sensors as a part of their Nikon Z mirrorless project but so far we have been shown just cheap zoom lenses dedicated to it.
Fortunately idependent producers try to save the day and Sigma is here an excellent example. They have constructed three well-put-together fixed-focal f/1.4 lenses for mirrorless cameras with smaller sensors – it is more than Canon, Nikon, and Sony combined...

We would like to thank K-Consult, the distributor of Sigma products on the Polish market, for a very fast delivery of the pre-production model of this lens. We do appreciate this tactics as it enables our Readers to get something more than just a dry list of parameters and a vague press release. Of course full tests will have to wait till we get the final specimen of that lens.
