Just knowing they are there will forever play on your mind , they might or might not produce artifacts ? , but
you know they are there and will never be satisified ,, .
Is it easy for you to return this ?
I would if it was mine .

At quick count without looking too hard, there would be about 10 specks easily visible. A more thorough inspection would probably reveal more.
Surely these things are put together in clean rooms?!!
On top of this, the objective element was rattling in the body, I was able to gently apply a quarter turn on the threaded retaining ring to bed it home.
My question is... should I be concerned? Will these have an affect on contrast etc?
As much as I would hate to have to do it, should I be returning it to Europe for a replacement?
I would try taking a photo(s) but don't like my chances of getting anything usable.
