I also may as well ask out of curiosity what would a digital back run me for a mamiya 645 afd to lease or buy at the bottom end.
and
...it seems I'll need to get a dedicated film scanner at some point and I wonder if the price difference is close enough that it doesn't make more sense to get a digital back.
Hi John,
This is exactly the dilemma/decision I faced a year ago. I did a
tonne of research on digital backs, and scanners better than my Epson 4990. I went the digital back route.
"At the bottom end" as you sweetly put it, there are some used "bargains" to be had for 645 AFD digibacks. I got a just-serviced, low-mileage Kodak DCS Proback 645M for €2600 including customs tax etc., and I haven't looked back (in 2 days time I will celebrate the anniversary of its "first light" on my AFD!).
More recently, in January, we got a new (€2000) EOS 5DII body. This happened during the "downtime" of my AFD having a shutter problem. Now you'd think I'd be gaga over this much fancier camera, but to be honest, other than astrophotography when I appreciated its incredible low-light/long exposure performance, battery life and live-view, I found myself pining for my Kodak 645M for daytime shooting! So I won a replacement AFD for a song last week, and baby's back in action again!
You might also look at the Mamiya ZD back. The Kodak bests it in some regards, but the ZD is a larger sensor.
