Wonderful at low resolutions; problems at high resolutions

Summary: I received and subsequently returned three consecutive copies of this lens from Amazon.com. Every copy had a very significant "back-focus" problem at f/4. When focusing on an object at f/4, the object in question will be slightly out of focus, while objects behind it will be in focus.
Summary: I have used Sigma's 50/1.4 on both Canon and Nikon mounts the old Minolta 1.7 and Canon and Nikon's own version. Sony is the worst of them. Sony is trying to get into the pro market but will need to do a much better job.
Excerpt: Was disappointed with the lenses. Maybe it was just me but my pictures were blurry. Great for low light situations such as in a gym. All the other reviews said it was a fast lense but couldn't get it to do what I needed-fast imaging. Will stick with my 2.8 lense.
Excerpt: The 50 1.4 lens is legendary in photography, and any company wanting to make its name in the industry should have a top notch one in there line up. Though I do favor Nikon, I do have other makes and I have a 50 prime for them all. After trying this lens out, I was left very disappointed.
Summary: Weis nicht ob ich ein "Montagsmodell" erwischt habe, oder ich einfach zu hohe Ansprüche an das Sony 50mm mit Festbrennweite gesetzt hab. Wie dem auch sei bin ich von der Qualität des sonst sehr hoch angepriesenen SAL50F14 voll enttäuscht.
