Here are the details on the four new lenses from Sigma – the three new mirrorless lenses (MFT & NEX) explain why the previous versions were 50% off in the past few weeks:
Sigma 30mm F1.4 DC HSM (see full press release) – Sigma’s new USB Dock, which will enable firmware updates and focusing adjustments, is expected to be available in coming months.– Sigma pioneered the large-aperture, APS-C format, standard lens category with its 30mm F1.4 lens in 2005. With new optical configurations of nine elements in eight groups, as well as rounded aperture blades, this updated lens delivers pleasing sharpness and a beautiful bokeh background. Its angle of view is equivalent to 45mm on a 35mm camera (which is similar to that of human vision), its minimum focusing distance is 11.8 inches and its maximum magnification ratio is 1:6.8. The lens’ optimized power distribution helps to minimize field curvature, prevent a loss of image quality at the edges of photographs and produce outstanding image quality. Its double-aspheric lens minimizes spherical distortion, astigmatism and coma, and its rear focus system prevents focus-dependent variation in aberration. Together, the new optimized auto focus (AF) algorithm and rear focusing system ensure smooth and accurate focusing. The new 30mm F1.4 is also compatible with Sigma’s new USB Dock, which will enable firmware updates and focusing adjustments, is expected to be available in coming months.
Sigma 60mm F2.8 DN– Featuring the natural perspective of mid-range telephoto lenses, together with a shallow depth of field, this lens allows the photographer to capture a single part of a subject with great bokeh effects. It has an angle of view equivalent to 120mm on the Micro Four Thirds system and 90mm on the E-mount system (35mm equivalent focal length). The minimum focusing distance is 19.7 inches; the maximum magnification is 1:7.2. This lens also contains Special Low Dispersion (SLD) glass, which helps minimize axial and transverse chromatic aberration.
