Perhaps so. But I can surely see a sharpness/resolution difference from a mediocre lens to a pro-type lens, when used on the *ist D. For instance I have compared my Tamron 28-80mm (50-100 USD lens) to my Tokina 28-70mm (250-1000 USD lens). There's a huge difference, I can assure you. So, if you're saying that it doesn't matter what you put in front of a 6MP sensor - it can't record much anyway, I totally disagree!
