Yesterday for few minutes, I managed to get my sweat and DNA all over the new mount P+S Technik have built for Nikon lenses and it is a huge improvement.
The locking pin arrangement remains however the lens is not longer rotated in the mount to secure it and is no longer latched by the locking pin moving in and out.
The mount now has a rotating collar which exerts positive pressure upon the bayonet lugs of the Nikon lens. The physical action of offering up and securing the lens is now identical to the rest of the system so there should be less likelyhood of operator mistakes.
There is now way the Nikon lens will rock in this mount with a follow focus driving it. The only movements of the image with focussing occur within the lens itself.
One thing for sure. In the event of a violent catastrophe, when the debris is swept up off the roadside or from the site of the airplane crash, the rear of the lens and the mount will be found firmly wedded together.
One upside of this style of mount is that there is no longer a wearing process occurring on the flange faces due to rotation of the Nikon lens.
The same care when offering the lens up to the mount needs to be taken as with the PL Mount or P+S Technik's own adaptor bridges. The locking pin must be in its correct position in the lens body otherwise the lens will not be secured and will rock on the pin.
The design on the surface appears to be very similar to the orientation arrangement used for the camcorder - Mini35 relay bridge piece except that the threaded rotating collar replaces the axial screws in applying the clamping pressure which secures the lens.
Gone for ever thank goodness, is that little awkard latch thing which is inclined to jam and frustrate the camera assistant with big fingers.
