It's only 2 months old.
What I thought were a few flecks of dust on the inside side of the objective turned out to be grease. Also the inside surfaces of the objective cell were covered in it, along with a few inches of the tube.
I can understand why someone might consider greasing a fine aluminium to aluminium thread (to stop it binding). I can even grasp the possibility they intended the grease as a means of trapping dust inside the tube (some DSLR's have a square of what resembles fly-paper for this reason).
But to put it anywhere near the objective...
And the retaining ring is hideously overtightened, I'm shocked the glass has not fractured.
Anyway off to Bintel now as its now fogged with moisture.
