I recently bought a Sigma Art Dc 18-35mm f1.8 HSM lens and i'm in love with its performance. Since i also own a very good copy of the Sigma EX DC 30mm f1.4 which is known for its center sharpness, I thought i'd compare the two lenses at 30mmm and the zoom at 29mm respectively. I tried to keep exposures similar, with no post-processing.

Note: The 18-35mm was hunting in the low light conditions present at the time, i focused one then disengaged the AF on the subsequent shots.

Thanks for these. At 1.8, it looks like the 18-35 is sharper in the center, which is impressive (barring focus anomalies).
