Sigma 30mm F2.8 DN A Sony E mount lens review: reliable performance, accessible priceBy Kevin Carter - Monday September 02 2013 Lens Review
Sigma’s range of DN A lenses have been designed for mirrorless cameras using both MFT and APS-C sensors, albeit with different mounts. As the equivalent to a 45mm on an APS-C camera we’ve tested the 30mm f2.8 on the discerning Sony NEX-7. Read on to find out how well it performs.
With their larger imaging circle we’re all accustomed to thinking how full-frame lenses can be used on cameras with smaller APS-C size sensors, providing the mount is compatible, so it comes as little surprise to see Sigma apply that principle to their DN series lenses.
These lenses are designed for mirrorless cameras available with mounts to fit either Sony NEX or the smaller MFT cameras from Panasonic and Olympus. On those cameras the 30mm (please note, we’ve already reviewed this lens with a MFT mount here) is the equivalent to a short tele (60mm) though on an NEX body using an APS-C size sensor it has a more amenable angle of view, equivalent to a 45mm. It has 7 elements (with 2 aspheric surfaces) in 5 groups, focuses to 30cm and weighs just 130g. It’s available now, for $199.
