Sigma 18-35mm f/1.8 DC HSM Lens Coming Soon?

Sigma 18-35mm f/1.8 DC HSM

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!
