Nikon 300mm f2.8 AF-SII Help required
Can anyone help with the following question. Recently purchased privately a 300mm f2.8 AF-SII. When looking down the lens there appears what could be a reflection. Best description is a small circle which looks like it is floating in the middle of the lens. It is not condensation.Not sure if this is standard on the non VR lenses, unfortunately I do not have any non VR's to compare with. Would anyone with one of these lenses mind having a look at theirs to see if it is normal.

Pulled out my copy of the 300/2.8 AFSII and took a look. I too see a circle that "looks" like it is very, very roughly about an inch (~25mm)wide that floats around as I look at slightly different angles. Don't take that measurement literally- I did not measure it. Just saying it is not huge, nor is it tiny
I would not worry about it. I would have never even questioned it if I wasn't trying to see the same thing in order to assure you your lens is just fine, at least in that regard.
Internal reflections are a matter of design, perhaps, and the quality of the lens coating(s) and internal "paint job" on the perimeter baffles. I suspect it is very, very unlikely that those reflections would vary from copy to copy unless Nikon made a significant change in manufacturing during the run. Something like going to a cheaper grade of "paint" or baffle material. And that, of course, is highly unlikely.
Or a prior owner "removed" the outer coatings by rough cleaning. But that would be very obvious by an inspection of the outer lens surface.
