Actually, it really wasn't bad at all relative to a stash of film in holders, especially a small laptop with good battery life. The QQQ was a nice solution a few years ago, a MB Air would work pretty well now I suspect, and at the end of the day, not all that expensive of addition in terms of the high-resolution digital world."Note that the scanning back is always tethered to a computer."
This must make it difficult to use in the field. Especially in inclement and cold weather. Have found little in the digital world so far that takes winter weather very well compared to the old tried and true Deardorff/Sinar gear.
With it you get,
1) Confirmed, onscreen digital focus
2) A fast preview scan for adjusting exposure, curves and composition
3) 11 true stops of DR that you could "curve" real time to match just about whatever look you were after.
4) Better than drum-scanned 8x10 quality (resolution)
5) The ultimate pano camera if you added the BL panning head
The downside was subject motion would impart mini rainbows in those sections of your image, and the paraphernalia required compared to direct single capture MF digital.
I liked the camera and if money were not an issue for me, I would still own a super 6K, the panning head, a view camera and three or four lenses...
