Not sure what category was best so I put it here. Please move it if it is in the wrong place.
My trusty old Nikon 60mm just started to make a knock/rattle noise. It is as if it were suddenly very worn. If I turn the lens over or shake it slightly I get light knocking out of it. The telescoping parts seem to have a bit of play, by feel only (not visually). It does focus sharp and all the aperture blades function normally.
We leave next Friday for out next trip and now i am worried it may fail while we are gone.
Has anyone seen/felt anything like this before?
Thanks in advance,
Erik
