Nikon 24-85mm f3.5-4.5G IF-ED
I bought this lens and i'm very happy with the pictures quality obtained. However, I notice that the front elements have a lot of free play, "loose wigling". I can feel they're loosed when I hold and move the lenses in my hand. Is it normal that "free play" for a "G" type or my lenses is defected? How about the upcoming model 24-120G which is similar? Any thoughs or comments? Thanks.
