@ Jan

Thank you so much for your input. I guess I know what im choosing to upgrade to. I've decided to go for the Tamron 17-50mm f/2.8 and the Canon 70-200mm f/4 L non IS. I know you said that having IS is a big benefit for. Tele-lens but I dont think I'll be using the Canon for night shots anyways, but if push comes to shove, i wouldnt mind bumping up my ISO. Thanks for helping me out Jan and for providing insight on all of my suggested lenses. If you dont mind me asking, is there a prime lens I should consider getting along side the Tammy and Canon combo im getting?
