Hello Forum Members,
Sigma today announced a constant F1.8 Aperture Zoom, the brand new 18-35mm F1.8 DC HSM Art for APS-C DSLRs.
While DoF is equal to F2.7 onto a FF Body, i asked myself ages if sometimes a lens like this would be possible,
congrats to the Sigma Engineers to develop such fast standart Zoomlens. I think that lens will perfect fit their
own Sigma SD1/SD1m (APS-C) or the new Nikon D7100 Body. It would be avialable for Canon, Nikon & Sigma Mount.
All Infos on dpreview, as usual:
