Conclusion: After a week of intensive testing, what have I concluded? By way of comparison with the Canon 1Ds, two things. Firstly, that while the 1Ds' $8,000 price tag seems high to most people, it is in fact a hell of a deal compared to what one has to spend for anything comparable, let alone better. Is the Kodak DCS Pro Back 645 better? Yes.
Summary: The Kodak Professional DCS Pro Back 645 was specifically designed with handheld photography needs in mind -- it's lightweight (1.7 lbs.) and the same size as a conventional film magazine. The Pro Back 645 is ideal for commercial fashion, high- end portraiture, and wedding photography. You'll discover astounding image quality and resolution with its 16 megapixel (4080 x 4080) sensor that can generate a 12-bit- per-color image, resulting in a 16-bit linear, 96 MB RGB file.
