The lenses I got 50mm 1.8 70-300 IS 28-135 mm al ef
Expect these older and mediocre lenses to be soft in the corners on ff, unless you stop down a lot, that's why I asked. Some lenses benefit from having only the center piece of the glass used, I had this experience with my good ol' 28-105 "golden ring" usm lens.
I shoot mostly landscapes and street photography
Ok, then the 5d2 it is for you, no question 'bout it if you want thinner dof for street. If you shoot iso 100 on tripod the 70d will also do of course, but then again so will any Rebel as you've demonstrated with the nice shots in your gallery.
