The lens I want is 200mm f/2.8L II USM... but it's over 600 on sale so I need to find a refurbished on or a used one :( I was taking pictures today in the agricultural center at the agility trials I volunteered at and all the pictures I got sucked :( so upsetting... When I got home and started to look through them I seriously wanted to cry. I had the camera in manual to have my aperture as open as possible but the lens I was using only let me do 5. I should have played around with it more.. but I couldn't use a high shutter speed because the pictures would be much too dark. This is what I got :/
