In the last year or so, Sigma has been making a real name for itself with lenses that are (relatively) cheap in price, but not in build or image quality. The company's 35mm f/1.4 full-frame lens was recently hailed by DxOMark as setting "a new benchmark for optical performance," and its 85mm f/1.4 has received similar raves. Most recently, the groundbreaking Sigma 18-35mm f/1.8 took the title of world's fastest zoom.
But all of those lenses are intended for DLSRs. Thus far, the company's offerings for Micro Four Thirds and Sony NEX cameras have been limited to two optics: the 19mm f/2.8 and 30mm f/2.8 DN primes. Both of those lenses are extremely sharp, but closely replicate focal lengths already well-covered in the M43 and NEX lens ecosystems, and have slower maximum apertures than their competition. Their saving grace has been their extremely cheap price: $149 each at most online retailers.
Today, Sigma has announced pricing for its third mirrorless lens. The 60mm f/2.8 DN. will hit the street at an asking price of $239. Part of the company's Art lens series, it produces a field of view equivalent to 120mm on Micro Four Thirds cameras, or 90mm on NEX models, meaning it's a short telephoto. The f/2.8 maximum aperture is still pretty dim for enthusiast tastes, but the longer focal length should help it produce beautiful bokeh anyway. Here's hoping it's just as sharp as the other lenses in the DN series.
On the outside, the body will be encased in smooth metal, like other DN lenses, and should have a metal lens mount. The optical design includes Special Low Dispersion (SLD) elements, which the company claims helps minimize axial and transverse chromatic aberration. Like virtually all other mirrorless lenses, the 60mm f/2.8 DN features a built-in linear autofocus motor that should provide silent focusing for both stills and video.
The 60mm f/2.8 DN will be available from mid-May, and can be had in either a black or a silver finish. For more information, check out Sigma's mirrorless lens page.
