I know CH doesn't trust light other than flash. Howsomever, I was pleased with 
the color I got with a cheap 4x5, 
daylight balanced light 'table' allowed to warm up for 10 minutes or so.

Using the original 5D, there's no live view, computer connection or not, so 
good light for focusing is an issue. 
Especially for those with less than perfect vision, enough light to 'stop down' 
the focusing eye is at least useful, 
perhaps necessary, for good results.

I used 7mm tube, bellows, 80/4 Auto macro lens, slide copier, cheap generic 
right angle finder with magnification and 
continuous light source. With decent light and viewfinder magnification, I 
found it reasonably easy to focus well. I 
think f8 is the sweet spot for this lens, but on 13 MP, I think f11 is just as 
good.

At f11, with slides from the same roll, I think it's safe to focus once, as the 
slide copier is good at holding them in 
the same place. Sticks of neg film seemed a little iffier to me because of the 
way they have to be adjusted for framing 
by hand.

If I were doing a lot of work with that set-up, I'd likely get a better finder 
magnifier. Well, if I were doing a LOT, 
I'd pop for at least a camera with computer connected live view.

For fine work on later film taken with good lens/technique, this method falls 
short of a good 4000 dpi scanner. For a 
sea of frames, especially slides, it's probably more than good enough. For 
older KR with ordinary lens, I just couldn't 
see any meaningful difference.

As CH points out, it's certainly faster than any other method of 'scanning'. 
Whether it's more time effective overall 
may depend on one's scanner and work flow. I've meant to compare it to batch 
scanning on the FS4000, but it seems I 
enjoy creating new images more than reviving old ones these days - and life 
happens. :-)

Hmmm, I'm wondering how it would work with the E-M5. 1:2 repro ratio would 
roughly fill a 4/3 frame, giving the output 
eq. of 1:1 on FF. That might be 50/3.5 territory, right on the border between 
it and the 80/4.
