My guess as to the reason why is that while the jury is out on the Canon 28mm vs Sigma 30mm as to who has the better IQ, most people on POTN seem to agree that the Sigma 50mm has better IQ than the Canon 50mm f/1.4.

So, in short: The 30mm has a counterpart from Canon, the 50mm doesn't really have one, which raises the resale value.

Disclaimer: Just what I've read on the interwebs. I've never used either Sigma lens myself so I can't really give my own opinion on it.
heard from a lot of people, not just from OCN that the sigma is considerably better than the nikon counterpart (50mm f1.4). better build, better IQ, etc

heard theres some front or rear focusing issues on some.. but a lot of people send it in to be calibrated? how does that work

Yep, this is apparently true, but in most of the instances where posters reported it, most said that Sigma recalibrated their lenses under warranty no problem. I believe that Marin used to have the Sigma 30/1.4 and had it successfully calibrated.
o. oOo... so the calibration fixes it.... oOo

Thanks. Honestly, I would get the Sigma 50/1.4 over the Sigma 30/1.4 if I were shooting a crop sensor, because you will get a shallower DOF wide open owing to the longer focal length (though the difference wouldn't be great). Also, the 50/1.4 has better overall sharpness, better bokeh, and suffers from less CA.

At f/2.8 on that lens, it's pretty sharp even in the corners, whereas at f/1.4 and f/2 the corners are fairly soft.

Check this out (zoom the slider from f/1.4 to f/2.8 and you'll see):

Of course, corner-to-corner sharpness for such a wide aperture isn't that big of deal since the corners of your shot are like to be OOF areas anyhow.

I've never looked in the corners except for the Sigma 12-24, which are absolutely abysmal at 12mm and wide open. Pure mush with 3-4 stops of vignetting. Still like it though.

Just so there's no misunderstanding, he meant the 50mm f/1.4 at f/2.8, not a 50mm f/2.8 lens (think Sigma makes one of those).
