okay, just came back from a camera shop, and the tech said there's condensation. so there's anything I could do? My friend told me I could use hairdryer to get the moist out. Does this work?


OP:
previously my manager asked me to sell his film slr gear; as some of you might know it is a Nikon, a 80-200mm and a 35-70mm. I brought it down to a camera show to see if I have any luck to sell to the guys there. While I test it one more time before I approach the used camera dealer, there is a noticable white tint as i look through the viewfinder with the 35-70mm lens; since the body is film, I cannot see the effects of the picture on a LCD screen. But I did pop in the 80-200mm and the "tint" went away. I peeked through the barrel of the 35-70 and didn't see anything 'white,' but I did spot 2-3 black particles. The lens looked fine with no white tint just 2 days ago.

coincidentally, I bought a nikon-olympus mount adaptor and plug the 35-70 into my DSLR, and the white tint does show up on the picture too. (I will upload an example later).

Could be a fungus.. I've heard of some growing on lenses that were not stored in good conditions.

fungus grow that fast? I mean, through the viewfinder there wasn't any white tint just a few days ago.

well, I have no other alternatives, except the hairdryer thing, but I rather not in case the heat will damage the optics.
