Re: Tamron 24-70 f/2.8 VC review

Your test shots don't look like it was done on a tripod. Worst yet it looks clearly evident that the Tamron shot has a slight angle showing DOF fall off on the left, sharpness on the right. That or it is decentered, but given that the images are not even lined up it looks more like they were hand-held ad hoc shots that can't be used to determined sharpness. Look how the Tamron gets sharper on the right side of the frame but softer on the left...center isn't as sharp either since it focused on the right side of the frame.

Also the Tamron was shot at 1/4000 vs the Canon's 1/3200. If shot at close to the same time-frame and lighting, it is the Tamron that is a slightly more transmissive lens which counteracts in part some of its strong vignetting since it may be a 'faster' lens overall. Finally throw in the fact that IS/VC enabled at high shutter speeds holds no advantage if not possibly a disadvantage in IQ if you didn't let the IS settle, etc (but clearly as shown by what is in focus on the right side may not make a big difference).
