I've currently got a Sigma 10-20mm and have used the Lee 77mm wide angle adaptor with it. I'm now changing my set up and will be mainly using a Canon 17-40mm instead. Does the 17-40 still need the wide angle adaptor or will a standard adaptor suffice. I believe that the wide angle adaptor sits further back on the lens than the standard version
