what i want is to be able to see 100% what is put through by the lens.
i don't want to second-guess the amount of coverage whenever i take a photo.
with the 7D's VF, WISIWIG, everything within the VF is the same as the preview seen on the LCD screen.
7D's VF:
1.0x/1.6 = 0.63 (63%)
6D's VF(rumoured):
0.71x/1.0 = 0.71 (71%)
iirc, the magnification is something to do with how big the subject appears within the VF(with a 50mm lens), relative to human eye?
so with the 7D's 100% VF i can see the full 63%. with the 6D, it is 71% worth of magnification, yes it is bigger compared to the 7D but with the former's 97% VF, i still do not see the full 71%, there will be 3% worth of coverage being left out at the sides of the image.
i'm not sure if you get what i mean, feel free to correct me if i'm wrong.
