I've personally tried this lens (a number of my friends own it) it's fantastic and i've been pretty much sold on it. But here's the question: How are the sigma and tokina and tamaron alternatives.
In terms of image quality (before post processing) ? I know the colour's going to be different between canon and the 3rd party lens.
Just wondering if it's worth it to save a few $$ by going non Canon.
I've searched through the threads and read a few comments so far. ANything else to add or consider?
oh i'm planning on getting the 10-22 but just checking out the alternatives
