The 45's AF-C issues stem from the huge amounts of uncorrected SA, most likely. The association between SA and problems with phase detect isn't exactly new. The article in question was written with DSLRs in mind, and I don't know exactly how that difference affects focusing with regards to SA. But the fact that this lens works better with contrast detect focus makes it more likely to me that SA is the culprit, as this is pretty common.
Well corrected 1:4 would be a different price point.
Bear in mind, too ... Sigma's building to the L Alliance. How many of those cameras are phase detect vs. contrast detect?
