I am about to get a 5D next month and plan on starting a business in wedding photography. I already have the 70-200 and plan on using it for the longer focal lengths and would like to know what everyone thinks is best for the shorter focal lengths but also covers wide angle. I;d like to hear from 5D owners who are out there shooting weddings already. Cost really isn't that important. I just want something comparable to the 17-55 which I;ll no longer be able to use(not with the 5D anyway) Sharp, fast and reliable is what I am looking for but something that goes as wide as the 17-55 on a full frame and as narrow as the 55mm end if this lens exists. Gracias!
