1. Introduction

On 21 of February 2017 the Japanese Sigma company launched as many as four new lenses. These were: the Sigma A 14 mm f/1.8 DG HSM, the Sigma A 24–70 mm f/2.8 DG OS HSM, the Sigma A 135 mm f/1.8 DG HSM and the Sigma C 100–400 mm f/5–6.3 DG OS HSM. The 135 mm model hit the shelves as the first and we’ve already tested it; then the telephoto Sigma C 100–400 mm f/5–6.3 DG OS HSM was released on the market. The idea behind that lens was to create a device not much bigger than popular, amateur 70-300 mm instruments but with a possibility of using longer focal lengths and obtaining images of better quality. We were very curious about the result so immediately after the first specimen of that lens had become available in Poland we set about testing it.

We would like to thank the Sigma ProCentrum company for sending us the final specimen of the lens in record time.

You are also invited to get acquainted with our test procedure, described in the article "How do we test lenses?" If you feel it’s still not enough, please go to our FAQ section where you can find some further explanation.
