Digital Camera World Verdict

The Sigma 30mm f/1.4 DC DN | C lens for Sony E-mount and Micro Four Thirds cameras is now available for the Canon EOS M system, where it goes head-to-head with Canon’s own EF-M 32mm f/1.4. The Sigma is similarly compact and lightweight, has the same fast f/1.4 aperture rating but only costs about half as much to buy. It’s a great performer and a proper bargain at the price.

In some ways, a fast standard prime such as the Sigma 30mm f/1.4 DC DN | C lens can be more versatile than a standard zoom kit lens that most of us buy with a mirrorless crop-sensor camera body. Sure, you lack the flexibility of sweeping through a range of viewing angles, but the fixed focal length of around 45mm (APS-C) or 60mm (MFT) gives a very natural perspective, while the wider aperture opens the door to a tighter depth of field. 

Indeed, with an aperture rating of f/1.4, this lens is about four f/stops faster than Canon’s 15-45mm kit lens, when used at the latter’s 30mm focal length. You’ll also be far more able to freeze action under dull lighting conditions, without the need to really push your camera’s ISO setting.
