I just like the Tamron 28-75/2.8 better. Aside from the build quality typical of these consumer grade lenses, it is sharp and reasonably contrasty.

well i have the 18-55mm EFS lense. image quality seems to be acceptable with the 18-55mm

i dont really need the USM as i tend to manually focus 95% of the time, but am semi-unhappy with the focus ring on the 18-55mm. it's touchy, choppy, and can be easily jossled out of focus ( loose ), but i have gotten used to it.

so would the image quality be substantially better than the 18-55mm?

i'm not a lense expert
