So far the market of mirrorless devices has been treated by Sigma with reserve. It’s true, they have produced a series of primes as fast as f/2.8 with focal lengths of 19, 30 and 60 mm but these were done occasionally so to speak, being just a part of a project concerning optical constructions for their Foveon sensors cameras. Still remembering that the 2.8/60 model fared in our test exceedingly well we did wonder what would happen if Sigma started to treat mirrorless instruments more seriously.

The launch of the Sigma C 30 mm f/1.4 DC DN which happened in February 2016 was the first signal that their approach toward that market segment changed. It is a completely new construction designed for mirrorless Sony and Micro 4/3 cameras. The move is still not exactly strong because the lens is considered to be among Contemporary (C) series devices, aimed at amateurs. Even if it doesn’t belong to the more advanced Art line (A) we were very curious how it would perform in our test.

We would like to thank the Sigma ProCentrum company for a speedy delivery of the final specimen of the lens which we got for testing purposes.
