Im not a MF owner..been close a few times but still try to stay educated about MF. I look at the new IQ2 series and I think they are a great offering..wireless is so cool. I am a bit perplex'd with the Achromatic model. Its a digital back so we are talking about pixels and electronic processing, not film..SO why is a black and white model offered if one can obtain the same results in post or set your IQ back to render in black and white only? True blacks, the blackest blacks and whitest whites, is that not available in black and white mode on a standard 160 or 260?... NOW before I get hammered on that last statement...this is why I'm asking this question..what am I missing on this back and its abilities and technology?
