My Xsi is my first DSLR and I am seriously considering upgrading from my Xsi to a 50D, jumping over the 40D. As far as 100% crops go, what kind of image quality improvements can I expect. I don't know anything about sensors and sensor quality so any links will be helpful. Is the XSi that much worse in image quality than a 50D?

I tend to crop heavily because I dont know much about composition at this point and would like a sharper result from the body. I know someone is going to tell me to but an L lens, or take a composition class but thats not my question.

Thanks for the help.

No, the camera will probably not produce shots that were discernibly sharper. It has a higher FPS rate, better focus, more rugged, better ISO, etc.

But it won't give you sharper shots. It will give you more pixels to crop, but that's about it imho.

I to am upgrading to the 50D but not because of IQ but because of speed, ISO noise, MA and others. I have several friends that have both and they say the IQ is comparable with the 50D getting the edge slightly. My XSi is great but I have outgrown it for the types of things I like to shoot. IE: sports, BIF, Wildlife which sometimes needs lots of cropping. Also the 50D has better, faster AF for these situations.

I like all of the other features of the 50D, but I can see the micro adjust feature being a great asset.
So.. For a better image quality from a body, is full frame the way to go? I'm pretty much looking to jump to the 50D soon and in the next couple of years Ill make the jump to full frame if I see a need for it.

Image quality is practically identical. The body isn't the place to be looking for an improvement. I'm going to be the one to tell you it's the lenses that make the image quality difference. The 15mp doesn't give you any extra cropping room when it out-resolves the lenses you put on it. I love my 50D, but increased image quality over the rebels isn't why I bought it.

It may not be your question - but it is the only correct answer.

I found going from a 30D to a 50D all of my bad habits could not be over looked. The sensor resolves so much detail that slow shutter speed or camera movement really show up.That said my 50D made me become a better photographer.

I have both the XTi and the 50d. Quality is excellent in both cases (XTi to ISO1600 and the 50d to ISO3200). Usability (camera features not related to image quality) of the 50d is much much better than the XTi. Two examples, one with the 50d, the second with the XTi of the same subject, both taken with the EF-85 f1.8. I'm using both of them in a regular basis.

Here are the 100% crops of the previous images. The first is from the 50d (at f1.8) the second from the XTi (at f2.5), both cases at ISO100. You may appreciate the larger resolution of the 50d, which at the end is only 22.5% larger on each dimension. Also, the 50d image is cleaner in terms of noise.
