>>3543804The design seems similar to a Pentax 67 or Pentacon Six with a large focal plane shutter. Would be interesting to know if it had a cloth or metal shutter.
I wonder if that wasn't abandoned because Nikon figured their design wouldn't be all that competitive with other MF cameras.
Complex glass formulas don't matter all that much for MF and I guess the one thing Nikon's known for (building rock solid cameras) might have ended in that camera being ridiculously heavy.
Combine that with a relatively small and shrinking market and I can see why Nikon didn't bother.
