I've had my eye on two lenses for a while: the Canon 70-200mm f2.8L IS and the Canon 24-70mm f/2.8L. I've bought all of my camera equipment from amazon up to this point because they always manage to have by far the lowest prices on new equipment. Within the last week or so, I've noticed a price explosion on Canon equipment from Amazon. For example, the 70-200mm f2.8L IS was $1449 on January 12th. Now the price has skyrocketed to $1699. That's a nontrivial increase of $250. The 24-70mm was $1028.99 in November. Now it's up to $1199. Both of these new Amazon prices just so happen to be the exact same price as both Adorama and B&H. Does anyone know what is going on here?
