My impression is the glass has copy variation. Mine seems good enough to me. Don't be fooled by its 55mm filter thread, the glass is huge and heavy. I feel almost like hold a 85mm 1.4 Lens. but it does have some play, which is not surprising for the amount of glass inside. Build quality is good but not up to Leica or even ZE/ZF standard. As I feel the focus is very smooth without enough Damping. (could be just my copy, which also show inconsistency at around 1M)
ah, missed this post when i was asking you about how you felt about the rokkor vs the nikkor. for some reason i stopped getting notifications for this thread.
sounds like your rokkor's helicoid was probably relubed with the wrong grease. rokkors typically have stiffer damping than most other lens brands from the same time period and it definitely shouldn't have any play in the focus.
