I bought my first 17-40 back in 2006. I used it mainly for the landscape work that I was doing then. I’ve used it on the Canon 5D, Canon 1Ds and the Canon 1Ds Mark III over four year period until tragically, in August 2010; it, along with the 5D that it was mounted on and the tripod; fell off a quay-side on Achill Island, Ireland – into the sea.
Fast-forward to September 2015 and I bought another used 17-40 – this one I kept until June 2016, when I bought a new 16-35 f/4 IS.
