Query: Awful lens

I bought EOS 20D and took this lens as well as my camera was without a lens. Most of the pictures shot with this lens are pretty blury. Even some of them when the flash was enabled were strange. Other times I managed to get a good picture or two. All in all, I am quite unhappy with this lens. Avoid it at all cost.
