Why do people still argue about equivalence?

You'd have to be an idiot to read these forums and not understand what it means by now. In order for 50mm f/2.8 on FF to be truly equivalent to 25mm f/1.4 on MFT you'd have to shoot FF at quadruple the ISO value, which essentially negates FF's advantage in image quality. If you want keep the two stops of IQ and keep the same exposure then you need to pay (in size and money) for f/1.4 on FF. If you're like me and don't want 95% of the image to be out of focus most of the time, then the ability to shoot f/1.4 on FF is pretty much irrelevant and in order to keep the same exposure, you will have to lose your advantage in IQ by shooting at ISO 800 instead of ISO 200.
