I am not sure what you mean if you have a kit lens, AND the 57-300 Tele. How long is the "kit Lens"?

One of the lenses I am currently looking at is the Sigma 8-16. WIKID wide and very sharp. That is why I need to know where your kit lens picks up at. If it is 18MM you will be missing 2MM. The 10-22 might be better for you.
