Hi all. just after some thoughts on the relative merits of the canon 40d and the 550d. I am currently using the 40d but had an injury which makes the weight and size a bit of an issue, in particular with larger lenses. I also am attracted to the idea of a walk around 24mm lens/ smaller camera combination. One option would be a digital rangefinder, but I still want the versatility of an slr. So....one option would be to get a 550d and a canon 24mm f2.8 to achieve a relatively light and useful combination for the style of photograpyy I am most drawn to at the moment.

I know there are features of the 40d I would miss, but I get the impression that the picture quality of the 550d is excellent. Any thoughts? Cheers.

p.s. am using a 24-105 L and 70-200 f4L, not exactly compact, so have been using the 50mm f2.8
