Conceder this, Bronica is out of business as of Oct. 14, 2005 and no longer supports their cameras. The only support you have is the parts already out their and non-factory repair. They made an offer to buy all unsold stock from dealers, this gave them some sort of legal loop hole so they don't need to make any parts and can stop selling parts in 2008. Mamiya is doing well and has a history of supporting their gear.
