Holy cow! What a lens for APS-C shooters if this is for real.
The Sigma 18-35mm f/1.8 DC HSM lens appears to have leaked out ahead of an official announcement. The lens would be a boon to Nikon D7100 and Canon 7D shooters if this turns out to be real. With the crop factor taken into account, we would be looking at a field of view equivalent of a 27-52.5mm lens on a full frame camera.
And that’s at a constant f/1.8 aperture throughout the range! [click to continue…]

Sigma’s refreshed Micro Four Thirds and NEX primes, the 30mm F2.8 DN and 19mm F2.8 DN lenses, will begin shipping later in March for $199 each.
These new lenses are priced the same as their predecessors and should be solid additions to mirrorless kits – particularly the NEX versions due to the limited selection of available lenses thus far. I own the 30mm in the older version in NEX mount and have been more than happy with the performance it delivered at the $199 price point.
You can order the new, improved versions from B&H at the below links.
