Rokinon 35f1.4 versus Sigma 30f1.4

Sorry, my bad, I thought you were referring to the new Sigma 35f1.4 that the prior poster referenced.

So you'd go for the Sigma 30... is it the manual focus/aperture that turns you off?  Do you have any expereince with the Sigma?  If so, has the edge softness been a problem.

Thanks.
