I think Sigma has finally got it right with their new Art series lenses. I am saving up for 35mm 1.4 and can't wait to get my hands on it. Does your camera have MFA feature?. I thought only the 50mm 1.4 have FF/BF issues not the 30mm 1.4 DC.
I'm waiting for a better price on the sigma 35 f/1.4. It out performs the Canon 35 f/1.4. But paying 900 for the sigma just seems wrong, but paying 900 for the lessor performing Canon seems like a bargain. Something is broken inside me.
Either way... my buy it now and new price point for the sigma is $800.
