Trying to look at the current dpr discussion at even wider angle Maeve's point, obviously, was about Nikon being past Canon. What he is doing, and I think it is quite obvious to everybody, is trying to prove Nikon is worthless. So, he invents situations which are quite rare in practice - and gains his score. Honest photographers can not ignore that he has his points, and start defending him. By that support minor things grow to big issues. Not that I think you need this explanations; but I just want to bring to your attention once more the sad fact that the only reasonable answer is something along the lines - "why Canon has that and that weak spots". But of course many of us do not want to bring discussion to that. So, ignore mode and warnings to others IMHO are the best reaction. I shoot wide angle wide open - but not with slr cameras. Rangefinders have better wide-angle optics, because they do not need the negative element to compensate for mirror chamber increasing working distance. The other reason is that shooting wide angle close the action is so fast that even short blackouts for mirror slap are bugging. Price, size, and weight(!) also matter here - 21mm f/2.8 Zeiss Biogon T* for Contax G vs. 21mm f/2.8 MM Zeiss Distagon T* for Y/C. And for "G" it is even autofocus Shooting wide angle is pretty often overhead, quite sometimes camera is held in one hand only, so the smaller is the camera the more chances are to get the shot - easier to aim, easier to hold, less vibration at slow ISO 1/30. So, rangefinders have quite an advantage. So, why Canon is not manufacturing digital rangefinders with external LCD viewfinders allowing live preview??
