They claim to be sealed against dust and moisture, something that’s so far eluded all of Canon’s EF-M lenses, although I couldn’t see a rubber O-ring on the mounts. The three new Sigma EF-M primes share several things in common: they all sport a bright f1.4 focal ratio that’s ideal in low light for for creating shallow depth-of-field effects. Canon’s EF-M 32mm f1.4 is a little smaller still at 61mm in diameter, 57mm in length, weighs 235g, has a narrower 43mm filter thread and noticeably closer focusing of 23cm. The Sigma 30mm is a compact lens: 65mm in diameter, 73mm long, weighs 270g, has a 52mm filter thread and a closest focusing distance of 30cm.

Thanks!ĮOS M owners looking for standard coverage now have an alternative to Canon’s own 32mm f1.4 with the Sigma 30mm f1.4 DC DN that at around $340 or 250 pounds is roughly two thirds of the price too. Buy it now! Check prices on the Sigma 30mm f1.4 DC DN at Amazon, B&H, Adorama, or Wex. Micro Four Thirds owners also have an arguably more compelling alternative with the Lumix G 25mm f1.7, but the Sigma 30mm f1.4 DC DN becomes seriously tempting for Sony e and especially Canon EOS M owners, for whom it comes Highly Recommended. The only real downside is a lack of optical stabilisation. It’s also a great choice for anyone filming pieces to camera from a tripod. Better still, it’s more affordable than most lenses with similar coverage and an f1.4 focal ratio, making it an ideal choice for anyone seeking a high quality standard lens that’ll out-perform kit zooms both in terms of subject sharpness and background blur. Whichever body you mount it on, the Sigma 30mm f1.4 DC DN delivers crisp results across the frame, with smooth and quiet focusing, while the f1.4 focal ratio provides plenty of opportunities for shallow depth-of-field effects. Summary The Sigma 30mm f1.4 DC DN is a standard lens for mirrorless cameras with 'cropped' sensors, available in the Sony E and Canon EF-M mounts, as well as for the smaller Micro Four Thirds format.
