Sigma 30mm f/2.8 DN A MFT mount lens review: Accessibly priced, compact and a good performer?By Kevin Carter - Tuesday July 30 2013 Lens Review
Sigma’s range of DN lenses are specifically designed for mirrorless cameras. The 30mm f/2.8 is the equivalent to a 60mm on a MFT camera and has recently been updated but, at $199, the price seems at odds with its new premium Art series label. Read on to see how well this model performs.
Although Sigma only introduced the DN range specifically for Sony E and MFT mirrorless cameras a short while ago, they've already redesigned the exterior of the lenses and integrated them into the firm’s new A series product line. The new, metaled exterior finishis more in keeping with the minimalistic design of Sony’s E-Series than either the Olympus or Panasonic models, but it’s well made and features a new linear AF motor for smoother, quieter focusing during video (and stills), and two glass molded aspherical elements (with one being a double sided asphere). The MFT mount model is the equivalent to a 60mm and has a minimum focusing distance of 30cm (11.8in), a maximum magnification ratio of 1:8.1, and comes in either a silver or black finish for $199.
