At the moment I have a 60d and a Tamron 17-50 non vc and a Sigma 10-20 which I am very happy with.
I have just bought a used Canon 5d3 body but as yet I don't have a wide angle lens to go with it, the only lens in my kit bag is a 100 f2.8 that will be usable.
I am on a budget of £500 so I am open to suggestions as to which to go for.
I was leaning towards a canon 17-40 that gets some good reviews, but also some bad ones ?.
Sigma and Tamron also do WA lenses in my budget, which is another option to look at.
The main use will be landscapes so a fast lens is not that important.
