From Canon Professional Network:
"Canon Ambassador Jeff Ascough has been photographing weddings in his distinctive, award-winning, documentary style with the EOS 5D Mark III DSLR and the EF24-70mm f/2.8L II USM lens: you can find out his opinions about working with the new standard zoom lens in an exclusive CPN interview.
The EF 24-70mm f/2.8L II USM lens is a smaller, lighter, more optically sophisticated and durable incarnation of a zoom lens that was already much favoured by photojournalists, portrait, landscape and wedding photographers."
