TDP has put up the ISO 12233 crops of the Sigma 24-105mm f/4 OS.
A bit better than the Canon 24-105L at the wide end, not too different in the middle, and a bit worse at the long end. Ata higher cost than the kit/white box price of the Canon 24-105L, I concur with the sentiment that this lens is aimed at Nikon users.
Something might be wrong since at 105mm the Sigma looks sharper midframe than in the center.
I'd like to wait and read DxO and Photozone reviews.
