Ray,
That's a good question! It seems like very few of the backs today can do this. I'd be happy if I could at least put the files straight into my catalog without having to convert them over. Neither the hasselblad files or the Leaf aptus 12 files can go straight into LR3. These digi back engineers probably drink their coffee black. eg. they haven't heard somebody order a half soy milk, half half and half latte with 1 pull decafe yet. Today we want to have options, and I'd like to be able to write uncompressed MOS or DNG to my CF card.
