DA 50mm 1.8 with dust inside?

I have been using a DA 50mm 1.8 for the last 4 months that I bought new. It was pristine when I first bought it, but I am now noticing some specks of dust inside the front element! I know it won't affect image quality but isn't this more common for old lenses to have this minor problem and not a near new one? I baby this lens and keep it very clean. I haven't seen any dust inside my 18-55 dal or 55-300 dal either. Has anyone else noticed dust in their DA 50mm 1.8, or have any idea how it could be getting in?

Dust happens. Every lens is different.

There are 2 kinds of lenses: those with dust and those that will have dust. Frankie says relax and enjoy :-)

I figured it was inevitable, so I guess I am mostly wondering if this particular lens may be known to have a chronic problem with it? It already has nearly as much dust inside as my 30+ year old Canon FD 50mm 1.8
