The effect seems to show the Tamron produces less artifacting. If this is because of improved resolution, well then Tamron has done well. If it is because of the Di (digital) design improvements to better accomodate the smaller digital sensors, then again Tamron has done a good job. This is the reason my friend now owns the Tamron 28-75mm F2.8L and my other friend is buying the same lens for his 10D. Both have their own studios in San Jose and this is their livelihoood so they don't mess around. If it works better or improves the image, they buy it.
