I have a ef 100mm macro lens that crippled my old t1i, so I haven't used it for a long time, so I sold it, and I am going nuts over the options I have, I kinda like the 6d a friend told me to look at the 7d but i think i am leaning towards a full frame for its upgrade ability. Ahhh driving myself nuts. Anyone out there who with both or the 5dmk3
