The only thing I have been able to surmise is that either (a) the lens (a 50mm Nikon lens) is not collimated or otherwise is now other than 51.6mm FL (I did notice that the front group was screwed in a little past where the selected aperture matched -- probably the work of that damn Canon ND filter); or (b) the rate of change in the RF mechanism is somehow wrong. While I would love to believe the problem is (a) (I unscrewed and reseated the front group), it had no apparent effect when I did a crude comparison of the film-plane focus and the RF (now when the RF says on at 6 feet, you have to turn the lens a little more toward infinity to get the film plane to focus). Also, the problem manifested itself with a Leica 35/2 as well. Neither lens presented a problem on my Hexar RF. ??? I just sent it all out to be fixed today, so I guess I'll find out.
