Canon "L" lenses which both work on Canon EF full-frame cameras and EF-S cameras like the 40-70 D series and 7D and a host of other models.
EF 400mm f5.6 L--This is a lightweight super-tele lens which is very sharp and auto-focuses very fast. It doesn't have IS but it is a GREAT lens for birds in flight because the IS doesn't make much difference for panned action shots. Also has the tripod collar, "L" case and a 77mm B+W F-PRO UV filter. The lens shade is built in--very handy!
Also have Canon 17-85mm, Tokino Pro 11-16mm.
