currently, I have the rebel kits lens, 18-55, 50mm 1.8 II, and tamron 18-270. I just purchased the 24-105 last week, but returning that because I'm looking to upgrade my body, thus figured, it makes much more sense puchasing a new lens along w/the mark ii as a kit (either 24-105 for $3k at B&H) or 24-70 w/canon's current rebate. * note, i'm looking to sell my rebel xsi, 18-55 and tamron 18-270 *
