Hi Matt
Congratulations – those L lenses sure deserve the reputation they seem to have garnered over the years. Yes, they are heavy; the other day I picked up my old Pentax *ist DS outfit and almost threw the bag over my head as I had subconsciously braced myself to lift the Canon camera gear.
Have you seen the review of the
Tokina on
Photozone?
You can also see the
Canon 10-22mm review there.
Cheers
Dennis
