The focussing barrel keeps unscrewing whenever I focus 'beyond' its limit.
What do I do to make it stay ?
Tried tightening but it still comes loose.
Is this a known QC problem? Googling throws up some remarks to imply that this is a known factory design weakness.
If glue is the solution, what should be the correct kind ?
Thanks in advance
