After much deliberation and research, I finally found a good starting lens. I am slowly but surely learning more about lenses, though I think it's going to be a long while until I have all the information committed to memory. It's pretty much like a foreign language to me.
Anyway, this is my new toy! It's not a Canon, but I think it'll work out just fine for my needs. Now I just have to wait patiently for it to get here.
I am anxious to see the differences between the lens I have now and this new one. I can't wait to get it and start playing!
