I just received my new Nikon 50mm f/1.4D AF Nikkor Lens. I bought it from Amazon.com I was so excited until I I opened the box and noticed that the front of the lens looks like it has Vaseline smeared all over it. Is this normal? Do I try to clean it off. If so how? And with what? Well I think I answered My own question.... I should have let the lens acclimatize. After the lens set on the counter for a half an hour. the jelly like coating has dissipated. The second uninspiring snap of the dog was taken with the new lens... I an happy now.
