Currently I have 2 bodies, a 5D MkII and a 7D. My lenses are 16-35 2.8L II, 24-70 2.8L and a 70-200 2.8L IS. I also have a 1.4 and the 2XII Canon extenders. I'm looking to pick up a used 300mm 2.8 non IS. I'm thinking of selling the 7D while it's still worth a bit of money before the MkII is released and the price falls to help fund the purchase. The 7D stays in the bag and I use the 5D MkII virtually all the time. Should I keep the 7D? It is nice to have a second body but not if it just sits it the bag.
