I learned the high-end EOS interface with my EOS-1 back in 1990 – a significant learnig cruve after many years with an F-1 – and I have always been very happy with it, more-or-less regardless of whether there was a mode dial or a button-and-wheel mode control. Currently I have a dual-format kit with a 5DIII and 7D, and I increasingly feel that Canon have lost their way with the ergonomics of the minor control interface – the "Too Many Buttons" syndrome. We now seem to have had the Direct Print button for ever, although other functionality has occasionally been assigned to it. A dedicated Picture Style button has been and gone on successive bodies, and we currently have the absurd Rate button on the 5D3, which cannot be made to do anythig in shooting mode and can be reprogrammed only to Protect in viewing mode. At the same time, although the button customisability in the 7D and 5D3 is much better than on earlier bodies, it does not go anything like far enough. For example, the nice prominent SET button cannot be programmed to do anything useful in shooting mode, only really to replicate the function of existing buttons. The different availability of space on the 60D and 6D has forced Canon to rationalise considerably on buttons. I wonder if others share my view that a considerably more disciplined approach (although not necessarily the same one as on those bodies) would improve things on the prosumer bodies in the future? That's not to say that all recent changes have been bad. I like the joystick (although I would quite like to be able to limit it to four-way operation) and I like the Live View / Movie switch and button. And, unlike some users, I have no issue with dual-function top buttons.
