I am intending to buy the canon 5d MK II and i was wandering if Tamron and Sigma make FULL FRAME lenses? As I would like to buy a lens that is 24-70mm f/2.8 ...however the canon lens is 2k ... however i have seen sigma 24-70mm lenses going for around 700-900 bux. Can anyone advise me how I would know if a particular TAMRON or SIGMA lens is full frame?
I know the canon range can be suggested by the L's series. I was thinking maybe TAMRON and SIGMA have a series of lenses that are full frame.
