I have a new T20 for use with longer lenses on my NN5. But it looks like the screw of the mounting rail is either too long or the holes in the T20 are a bit too short. It is not possible to tighten the adapter, there is still a little bit of space, even when tightening the screw very heavy.
Do I need another rail?
Is that a known problem?
Can I just shorten the screw 1 mm?
Any help is highly appreciated.
Best regards from Hamburg
