In my post from yesterday, I postulated that the new lens will have the same RF cam design as the old 90 Elmar screw-mount and the thin Tele Elmarit 90/f2.8, which is a cylinder. It will act on the cam follower in the eye attachment in the same fashion that it acts on the RF wheel in the camera. It will have the same bayonet pattern as the older 90TE. When mounted upside down on the eye attachment, it will show the distance scale for the close distances, and will act on the push-rod cam follower of the attachment to move the camera body RF wheel. > When mounted normally on the body it will show the distance scale from 1m to infinity and will act directly on the RF wheel in the body just as do the older lenses with a cylindrical cam. > > You are perhaps being mislead by thinking that the new lens will use a push-rod cam mechanism. > > Regards, Paul Connet > > Lucien answers Dan's comment: > >>Dan says: > > > No, I meant that it would seem that if the lens can mount in both the > > > adaptor and the camera body directly, then the mounts in the camera > > > body > > > and the adaptor can't be that dissimilar. > > > > Dan, > > They are. > > Compare the bayonet on the Macro-Adapter and the bayonet on your camera > > body. > > On the adaptor, the lock is on the opposite side as on the camera. > > Which means that on the Macro-Elmar 90mm there will be two cam at 180 > > degree of each other. > > One used when the lens is mounted directly on the camera > > and one use > > only with the adaptor. > > > > Lucien > -- > To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
