I took a hard look this weekend at a Fuji GW690 (1978 model) from a dealer I trust who said it was recently CLA'd. However, the aperture ring was difficult to turn. I did not purchase the camera because of this.

How hard should the aperture ring be to turn on a GW690? I'm comparing it to what I know best: Nikon AIS and Pentax 67 lenses. Your advise is most welcome.
