Swift 828HHS problem..? (1 Viewer)

Hello all! Decided to treat myself to some new bins and have picked up a pair of Swift 828HHS roofs. Build quality feels great and the new central diopter ring is handy - view through them isn't too shabby either! But....on close inspection of the objective lenses I can see that the lenses just under the front elements seem to be 'dirty' (for want of a better term). It's as if they've been breathed on and have not cleared. It isn't fogging - you look straight down the tubes and you can't see it, but looking from an angle those second elements appear like dirty windows. So, what gives? Should they be this way or should they be on their way - back to the store!? Any advice would be most welcome.

Regards,

Mook.
