Why not just shoot a 7II and scan the film?
Cost! I was spending AT LEAST $5,000 a year for film & processing, just for my personal projects, for the Mamiya 7II. Plus the time for 2 trips to the lab, cutting, digital contact sheets (negative film for me), storing, cost of film scanner and time for scanning, cost of storage ...
When I bought my Canon 1DsII, the breakeven - for the total cost of an $8,000 camera - was about 8 months! My actual cost for the 1DsII, for the 2 years I used it before I sold it was $1,500 per year. Or the equivalent of about 3 months of film cost only, for film that was not billed to clients. The next 9 months of personal use each year were "free."
(FWIW, I have a degree in photography, but I also have an MBA. There are some detailed spreadsheets back there somewhere -- was that around 2005?)
(I calculated my 6x7 film cost at the time at $1 per frame, 35mm at .33, for pro color film and developing. I averaged approximately 35,000 images per year with the 1DsII and later cameras. So if I actually had to pay for all the frames I did with digital - knowing that I shot more freely with digital than with film - that would have been $35,000 per year for 6x7, or about $11,000 for 35mm, for film & processing only.)
I had already gone to a fully digital scan & print process flow in 1998, so the computer costs were the same for digital or film.
I kept my two Mamiya 7II's for a full year after going digital, I just couldn't bear to sell them! I finally took them out after a year and went out to shoot. How strange! I had to load a different film just to change the ISO? I couldn't check exposure or get feedback on sharpness, composition, etc? I had to wait a few days to review the images? It really was a wierd experience after being fully digital for a year!
So, yes, a lot of nostalgia on my part. But my real world choices were 100%+ to keep the Canon 1DsII at the time, and to never look back. For prints up to 18x27 I was completely satisfied, with no preference for one system over the other, which was sufficient for 99% of my needs. For anything requiring more detail I turned to 4x5 film.
