RJ, here were my consideration for MF:
1. I would develop negatives in a local shop
2. I already have Canon 9000f scanner, which can scan film negatives. Not the best, but does a very good job
I don't expect a lot of change in quality going from 5dm2 to 1n or even 1v. Please, correct me if I'm wrong here.
I can get used Mamiya with 80mm or Bronica with 75mm both with film backs for approximately ~$300, which, considering cost of my other photo equipment, is not significant.
If I find that I enjoy MF and film, I can start moving in that direction and if I don't like, I can always resell for pretty much the same value.
