Steeeeed said:My own advice would be to get as much as you possibly can from your current body before upgrading. You say you have it in your head that you want a new body, but why? Does the current body limit / hinder you in any way? Is it likely that a new body will improve your photography? You put more into the picture than the camera. This is in no way a comment on your own ability btw.
You may be able to answer these questions, if so, grand, fill your boots.
Personally, I've realised what my body can't do but I know it's very strong in other areas / meets my needs. I'd be looking at circa £800 to upgrade body, then God knows what on lenses that can do the body justice. So right now I'm sticking with what I've got.
I've also just realised that this in no way answers your question but I've typed it now so you're getting it
I know what you mean, just a few things which would be improved. Lower light level shooting, sharper images, weather sealed, video recording, larger screen, real time images through the screen etc. I can probably get my money back on my camera and get a 7D for 700, meaning for 500 quid improving the body would probably improve my shots more than a 500 quid lens.
