SIGMA 30MM F2.8

Has anyone used the SIGMA 30MM F2.8 EX DN LENS for micro four thirds with BMPCC or BMCC? I was considering this for closeup shots as this has the crop factor close to the 85mm on a 35mm full-frame. Any thoughts or experience with it? How does it perform compared to the new Art version on a GH2 or GH3?

I shot this entire video on the new art 30mm 1.4. I really like it. I didn't even know they made a 30 2.8 though.

Thanks for sharing this. Love the flares! Sigma makes 19, 30 and 60mm f2.8 for NEX and MFT mount and the price is very reasonable. Can I ask which camera did you use?

with my BMPCC, no Iris control with either the Sigma 19mm 2.8 EX DN or the 30mm 2.8 EX DN lenses.

Thanks, I found out yesterday and will be returning the lens tomorrow.
