Originally posted by braxus I have debated going back to the older P67 cameras, as I had one previously and it had no issues.
Going back to the Pentax 6x7 or 67 cameras will not put you in an easier situation. Both cameras, especially the 6x7, are now quite old (51 years for the Pentax 6x7, 31+ for the 67). Eventually fault and failure will conspire against you to the point where the only option is to have repairs done with parts salvaged from like cameras, the cost of doing so likely to be greater than the worth of the camera at any point. This cross-species repairing will introduce further unreliability because engineering changes occurred around the Pentax 67, especially with the shutter, winding mechanism, shutter speed dial etc.
At the end of the day, the cameras are going to cease to function well irrespective of the number and involvement of repairs, and digital, as unpalatable as it may be to many, will be the only avenue left. Keep an open mind.
