I’m looking to sell my Canon 70-200mm f/2.8L IS. It’s a great lens, has normal signs of being used (paint rubbing) but the glass is absolutely pristine! I’m looking for downgrade to a 70-300mm IS DO as I’m doing a round-the-world trip this summer. I’d be interested in a swap with some cash or an outright sale. The lens is a few years old and was bought in the UK.
