So after using liveview to check the focus on my 21mm, it turns out that it was fine. I was just an idiot thinking that the Viewfinder on camera should have the correct corresponding focus with the lens. I guess it's a keeper! Thanks to Akul, CVickery, Carsten, and Mescalamba for pointing out my error.
I had the same thing. It became even more obvious after installing a KatzEye split-prism screen - the focus in the viewfinder did not agree with the focus in the image. I talked to KatzEye and they said this is pretty common. These days, camera makers don't bother to calibrate the viewfinder for manual focus very accurately, because the vast majority of photographers use AF. Eventually I calibrated my viewfinder by putting shims between the prism and the focus screen. It's very precise now, but it required some good nerves to mess around in the mirror box. In any case, these alignment issues are never the fault of the lens.
