Can someone diagnose this lens "spot" ?
1 week ago

I just received my used 1 yr old Nikon AF 16mm f/2.8D fisheye lens via the postman 2 hours ago , bought it from ebay. First thing i noticed was a "spot" that appears to be under the front glass. I shot this 20 second video on youtube against a white wall at different apertures and the spot shows clearly. Can someone give me some idea of what this is and how i might get rid of the spot please ?

It seems this wide lens cannot take a filter on the front , and there is seemingly no way to "get under" the front glass to clean this annoying spot .

I only bought my first lens a few weeks ago , so i am far from an expert . Any help would be appreciated , i paid $650 for this   16mm f/2.8D fisheye lens , i'm quite worried atm 

Here is the link to the video.
