Once again not qualified to comment why but they just were.

Like I said I have both scopes referred to but with 42 and 50 mm objective lenses respectively, I don't observe any distinguishable quality in the glass but with the 3-18 you need to use the side focus to get the best out of it because the scopes parallax is configured differently, it's entirely plausible that with 42mm (2-12) and 44 mm (3-18) objective lenses the 3-18 suffers at magnification greater than 12x due to inherent reduction in the exit pupil and this is maybe what has caught your eye.
