The 400D wins in terms of picture not so much, but in terms of ergonomics - a huge step forward (two wheels, an upper display, direct parameter control buttons), so for me this is a new level. As far as I can understand regarding modern *00D models, there is no difference at all in the picture, but for me, in any case, ergonomics and ease of control would be the decisive argument when buying, because in many respects this is what determines the pleasure of working with the camera. The next step for me is only a full-format matrix, on which the picture goes to a new level.
