We've just published our first impressions of shooting with the Sigma 18-35mm F1.8 DC HSM | Art. We've tried to express just why we're so excited about this lens, that offers APS-C DSLR users access to some of the depth-of-field and low light capabilities that full frame shooters get from their F2.8 zooms. We're hoping to hear about pricing and availability soon so, in the meantime and in the light of our first impressions, what would you expect to pay for this lens? Let us know in the comments.
