Photographers: In your experience was it the body of the camera or the lens that ultimately produced your best images?

So as you know I’m thinking of downgrading from 60D to 10D or Nikon D40. The 60D is loaded with functions, just stacked with key features that the downgrades wouldn’t be able to offer.

However also in my experience I know the difference between a good photographer and novice is their use of lens and knowledge of aperture, iso, shutter speed, lightning techniques etc.

Have you ever had experience where the body of the camera was just so awesome without it’s functions and capabilities none of the lens would matter? Or vice versa perhaps? Your lens was so awesome it just makes puts the body to shame? Or do you find a balance and are just super manual with your photography that it doesn’t matter what you shoot with?

Please state whether you are digital or film person, or however you answer the question, as long it pertains to your camera style.
