We have a Canon 5dMKII, and while it is a great camera, we haven't been able to find lens, other than Canon lens, that work with the full frame shooting? Does anyone know what other lens manufacturers make lens that will work? We have a couple of Sigma Lens and a Tamron lens that work great with our Xsi, but definitely vignette with the 5D.
Thanks for any help. Shirley
