I agree 100% with Saul... getting lenses of the same make as the camera-body is always the best, in terms of quality. I can also assure you that you won't be disappointed with the F90x (N90s)... I've had mine since this past Christmas, and it hasn't let me down... alongside the 80-200F2.8 (I can't praise that lense enough!) and my 35-70F3.3-4.5 Nikkor lenses. The latter was rather inexpensive, however I wouldn't mind owning the 28-105... just so I don't have to change lenses all the time, like I do now.
What other people think of you is none of your business!
