hi everyone! So heres my problem. Ive got roughly $1200 to spend on good lenses for my new 10.1 canon rebel xti. i have two lenses already, one is a tamron 28-80mm and can i just say- VERY disappointed. i need two different types- one for close close shots to like 5 feet or so away. and then one for further away I'm s using this camera to shoot senior portraits, baby announcements, engagement pictures and eventually weddings I've just got into photography and tho i'm still learning about cameras and whats what, I got into it because I'm awesome at photoshopcs3 and other software. what i would like to do, however tho, is to take pictures with a quality camera and lens that will require minimum editing. Suggestions?
