On the Leica R case, some suggested that because of the internal focus mechanism that the focus action can\'t be more dampened. I used to have the Leica 100 APO, and it was just right. My Contax 35/1.4 was serviced by Henry Scherer. He said that a properly lubricated Contax should have quite stiff action. The Contax 21/2.8, an internal focus lens, has a rather loose action as well, at least on my copy.
On the other hand, the focus slack on the ZA line is minimal at best (still way better than the Samyang I have). More importantly, they are while quite consistent: 85 is a normal while the 135 is an internal focus, and they feel the same to me.
hmm, i\'ve never used any of the R\'s with internal focusing so i can\'t comment (from a mechanical perspective the idea that they couldn\'t be damped sounds ridiculous though. maybe harder to service?). all the MF brands i\'ve used have been very consistent unless the there was helicoid or grease problem (which can be common in poorly maintained 50 year old lenses) and none have had any slack whatsoever unless there was helicoid damage or a loose screw somewhere. i find the ZA lenses to be better than any other autofocus lenses i\'ve tried, but still pretty annoying (infinitely better than focus by wire though).
