A close eye on the new A-mount Sigma lenses (via Photoclubalpha).


David Kilpatrick from Photoclubalpha (Click here) wrote an interesting article about Sigma. The three new A-mount lenses bring many innovations and David is talking about every detail. Particularly the 35mm f/1.4 is getting a lot of attentions. Sigma said it will beat the image quality of the Nikon 35mm f/1.4 lens.

Reminder, these are the thre new Sigma lenses (no preorder and price available yet):
17-70mm F2.8-4 DC OS MACRO– This new Contemporary lens is designed for cameras with an APS-c sensor and covers a range equivalent to 25.5 to 105mm on a 35mm camera. An upgrade to its predecessor, which was released in December 2009, this general purpose lens offers a new design and a more compact build.
35mm F1.4 DG HSM– This Art lens provides photographers with a state-of-the-art alternative to the more conventional 50mm. This lens’ axial chromatic aberration is minimized, which renders a cool and smooth out-of-focus image. At low apertures, it can perform like a wide-angle lens; when opened up to F1.4, it will provide background bokeh and make the subject pop like a mid-range telephoto lens.
120-300mm F2.8 DG OS HSM – With redesigned mechanics and performance, this Sports lens is an update from its predecessor released in February 2011. This high-performance lens eases difficult shooting conditions by offering a maximum focal length of 300mm and a wide-open aperture of F2.8. This lens, like the other Sports category lenses to come, is dust and moisture resistant, and allows users to adjust the focus speed and the focus limiter via a button on the lens.
