I was not really doing this for photography, but to test the sharpness of the lens, which was not really working on my favor. It is a Canon EF 70-300mm 1:4-5.6 IS USM. Yeah I know it's not nearly one of the best out there, but it's fun to play with for a beginner and for a cheaper lens. I am saving up for some better lenses. I am looking for some great sharpness!! I've heard a few suggestions but please share any suggestions or comments on good sharp lenses that show good contrast for a Canon EOS Rebel XSi.
