I am very grateful for your input. PLEASE keep it coming. I have the USB dock and will get to work on it; will also try lensAlign. I admit to a high degree of extreme paranoia about sharpness. This is my problem, not Sigma's. But I just finished a 2-hour theater shoot with the 70-200 and 24-70 and I saw lots of liquid and fine red capillaries on eyeballs, handheld, wide-open (the aperture, not the eyeball); and so my paranoia is bone deep. I'll give it a try though. Thanks again, keep it coming.
