Have you seen this week's Amateur Photographer magazine? It shows that noise-wise (and IQ and resolution) the 5D still beats the D300 and the 40D. It really is impressive, so no wonder that in terms of noise and sharpness of my images, the A700 simply cannot compete.

Having said that, there's no point having the best camera in the world if it never gets taken out of the cupboard. I prefer the light weight and size of the Sony. Having said that, if they replace the 5D with a camera equipped with a decent LCD, I might be tempted to get one for my 17-40mm f4L lens.
