Sigma 30mm f/1.4 Contemporary DC DN

The lenses of the Comtemporary series from the Japanese company Sigma are aimed at amateur photographers and do not particularly stand out from their peers with outstanding optical characteristics. However, this did not prevent the Sigma 30mm f/1.4 DC DN Contemporary fixed lens from taking first place in the podium of the best optics for Sony mirrorless cameras in 2016 (according to the authoritative resource DxOMark).

High luminosity

In the version for the Micro 4/3 system, the equivalent focal length of the fixed lens is 60 mm. This means that it can handle both everyday scenes and more complex portrait photography. No joke, the model is the most aperture-fast in the budget optics class, and also captivates with its 9-blade diaphragm structure. Thanks to such data, it is possible to effectively separate the subject from the background and get fabulous bokeh with smooth "rounds" in the out-of-focus area.

Character of the drawing

The aperture of f/1.4 is quite workable for the Sigma 30mm f/1.4 DC DN Contemporary. However, the image when shooting at an open aperture can be spoiled by vignetting, and the autofocus system sometimes stubbornly refuses to catch objects in the distance. It is enough to cover up to f/1.8 — and all problems are reduced to “nothing”. The picture literally “rings” with sharpness at any settings up to f/8.

Stepper drive

The autofocus system of the fixed lens is driven by a stepper drive, which ensures smooth focusing during video recording and fast focusing during photo shooting. If we take into account the Micro 4/3 system, then given the price and the nature of the design, there is simply no equal to the Sigma 30mm f/1.4 DC DN Contemporary.
