Help please on Nikkor 35-70 F2.8
Hi all, and thanks in advance for your inputs.
I've just got a new 35-70mm F2.8 Nikkor. When not mounted on the body, and inspected via the rear end while the front end is pointing towards a light source, I noticed some small dots or particles. The particles or dots are colorless (probably because they're too small), and if I zoomed in and out while looking thru the rear end, directly at the light source, they are visible. These particles are evenly distributed across the glass, and are not randomly located on the glass. I showed this to a movie camera friend of mine, and his comment was that this is normal attributes of the glass. The word he used is "crystallization of the glass".
The dots are not visible thru the camera viewfinder. I do not have reference pictures nor anybody that has this lens that I know of. Therefore, I would greatly appreciate it if anyone who owns this lens could tell me that this is normal, or abnormal. Again, thanks in advance fellow Nikonians.

It is more likely irregularities in the coating. That lens you have there is a barrel lens, those types of lenses are prone to accumulating dust within the barrel because they work like a suction pump... Watch for that.
You're ok, the lens is probably fine. If you're really concerned, go back to the store and insist they let you look at a couple of specimens to compare.

Take Frankie's advice and visit your store.
I own one of these beauties and it works not just fine but superbly well, whether mounted on the F4s or the F5.
Have a great time

Thanks for the inputs. I did take it to a Nikon service center here and they concluded that the element needs replacing. Well, back to the stor Again, thanks guys.
Oh, by the way, I also asked the service guy to check my F100 body. Bought just a month and a half back. Guess what, over exposure here and there. Geez, just out of the box.
