DxO Labs recently put the new Sigma 18-35mm f/1.8 lens to the DxO Mark test. The results?
It’s the sharpest APS-C lens ever tested, and it rivals the wide open sharpness of the new Canon 24-70mm f/2.8L II USM lens (and that’s when the Canon lens is tested on the full frame 1Ds Mark III), and of course, the Sigma is more than a full stop brighter at wide open than the Canon.
When you compare the lenses on the same Canon 700D body, the Sigma scores much higher.
All early reports of the Sigma 18-35mm f/1.8 DC HSM seem to point in one direction – it’s a killer lens. And better yet, it’s a killer price at $799.

This lens looks amazing! If they ever make anything like this for full frame, i’ll be one of the first to pre-order
