I am not assuming anything - I just looked at the three rf's I have in the house- a canter beauty, a QL17 and a Bell&Howell Canonet 19. I have handled/shot/played with countless others - but I do not have them on hand. All have close to standard lenses (40mm - 50mm range) and all have no more than a third of a turn "lock to lock" with the QL 17 being about 1/4 of a turn. All the lenses in that focal length range I have (a Nikon, two Canons, one Helios and a Minolta) range from almost a full 360 deg to 3/4 of a turn. I would say its safe to venture a generalization like the one I put forth, since in most cases, it will be true. I never claimed it was a hard and fast rule - but something the average person will find in the average 35mm rf.
