Korean website lcap.tistory.com has published what it claims are sample images from the new Sigma 18-35mm f/1.8 DC HSM lens, which purports to show its performance in a range of different shooting situations, on both a Canon EOS 600D and 5D Mark III. We doubt very much that the site had Sigma's permission to publish the images from a pre-production lens, but if you're curious, you can click the link below to go to the original 'preview' at lcap.tistory.com.
