Hi i just got a Canon 20D digital SLR camera as a gift and my friend gave me a Tamron 24-74 2.8 zoom lens to go with it. she said its used on Nikon to. Has anyone ever used this camera before? is it good for photography? I heard its pretty nice but i want to know what everyone thinks. I also was wondering what kind of photo editing i could use. something not expensive. just something temporary right now. I do have this program called Irfanview. i'm so excited i cant stand myself but should i be working myself up for this?
