I guess my question would be...why do you feel you need a new body? Given the situation, I will opt for new glass just about every time, but then that's just me. For me, glass is forever, well almost, but bodies come and go, I mean look at the evolution of the Rebel series alone. If you were going to opt for a new body which one would you go for and why? What do you have in mind for new glass and why? I do believe, as others have stated that new glass on an older body, will give you better images, but I also think that maybe it depends on the "new glass" as well...an "L" series lens should definitely give you a better image on an old body. I agree an XTi is a little old in terms of the technology, but a lot depends on what you think a new camera will do for you now versus what a new lens will do for you now. Just for comparison, your camera has the Digic II processor in it which is the same as mine, a 5D FF, so I can hardly wait until the Mk III comes out. I opted for glass instead of going for the 5D Mk II, which would have meant doubling of the number of pixels in the sensor and going to a Digic 4 processor, but I was happy with the Mk I, so I opted for glass...glad I did, because I now have glass e.g., the 16-35 f2.8 L IS Mk II wide angle lens which I would not have, had I opted for the Mk II. That is my story, but, of course, your story is up to you - what do you gain from a new body vs. what you think you will gain from new glass. God luck. :thumbup:
